General term for a number of inherited defects of amino acid metabolism in which there is a deficiency or absence of pigment in the eyes, skin, or hair.
Heterogeneous group of autosomal recessive disorders comprising at least four recognized types, all having in common varying degrees of hypopigmentation of the skin, hair, and eyes. The two most common are the tyrosinase-positive and tyrosinase-negative types.
An enzyme of the oxidoreductase class that catalyzes the reaction between L-tyrosine, L-dopa, and oxygen to yield L-dopa, dopaquinone, and water. It is a copper protein that acts also on catechols, catalyzing some of the same reactions as CATECHOL OXIDASE. EC 1.14.18.1.
Syndrome characterized by the triad of oculocutaneous albinism (ALBINISM, OCULOCUTANEOUS); PLATELET STORAGE POOL DEFICIENCY; and lysosomal accumulation of ceroid lipofuscin.
Involuntary movements of the eye that are divided into two types, jerk and pendular. Jerk nystagmus has a slow phase in one direction followed by a corrective fast phase in the opposite direction, and is usually caused by central or peripheral vestibular dysfunction. Pendular nystagmus features oscillations that are of equal velocity in both directions and this condition is often associated with visual loss early in life. (Adams et al., Principles of Neurology, 6th ed, p272)
A condition caused by a deficiency or a loss of melanin pigmentation in the epidermis, also known as hypomelanosis. Hypopigmentation can be localized or generalized, and may result from genetic defects, trauma, inflammation, or infections.
The common orally transmitted traditions, myths, festivals, songs, superstitions, and stories of all peoples.
Melanin-containing organelles found in melanocytes and melanophores.
Nystagmus present at birth or caused by lesions sustained in utero or at the time of birth. It is usually pendular, and is associated with ALBINISM and conditions characterized by early loss of central vision. Inheritance patterns may be X-linked, autosomal dominant, or recessive. (Adams et al., Principles of Neurology, 6th ed, p275)
Color of the iris.
Mammalian pigment cells that produce MELANINS, pigments found mainly in the EPIDERMIS, but also in the eyes and the hair, by a process called melanogenesis. Coloration can be altered by the number of melanocytes or the amount of pigment produced and stored in the organelles called MELANOSOMES. The large non-mammalian melanin-containing cells are called MELANOPHORES.
Coloration or discoloration of a part by a pigment.
Autosomal dominant, congenital disorder characterized by localized hypomelanosis of the skin and hair. The most familiar feature is a white forelock presenting in 80 to 90 percent of the patients. The underlying defect is possibly related to the differentiation and migration of melanoblasts, as well as to defective development of the neural crest (neurocristopathy). Piebaldism may be closely related to WAARDENBURG SYNDROME.
Insoluble polymers of TYROSINE derivatives found in and causing darkness in skin (SKIN PIGMENTATION), hair, and feathers providing protection against SUNBURN induced by SUNLIGHT. CAROTENES contribute yellow and red coloration.
The electric response evoked in the cerebral cortex by visual stimulation or stimulation of the visual pathways.
A form of phagocyte bactericidal dysfunction characterized by unusual oculocutaneous albinism, high incidence of lymphoreticular neoplasms, and recurrent pyogenic infections. In many cell types, abnormal lysosomes are present leading to defective pigment distribution and abnormal neutrophil functions. The disease is transmitted by autosomal recessive inheritance and a similar disorder occurs in the beige mouse, the Aleutian mink, and albino Hereford cattle.
Coloration of the skin.
Membrane proteins whose primary function is to facilitate the transport of molecules across a biological membrane. Included in this broad category are proteins involved in active transport (BIOLOGICAL TRANSPORT, ACTIVE), facilitated transport and ION CHANNELS.
Abnormal sensitivity to light. This may occur as a manifestation of EYE DISEASES; MIGRAINE; SUBARACHNOID HEMORRHAGE; MENINGITIS; and other disorders. Photophobia may also occur in association with DEPRESSION and other MENTAL DISORDERS.
Recording of nystagmus based on changes in the electrical field surrounding the eye produced by the difference in potential between the cornea and the retina.

A family of fresh water fish in the order CHARACIFORMES, which includes the Tetras.
The state of estrangement individuals feel in cultural settings that they view as foreign, unpredictable, or unacceptable.
An enzyme of the oxidoreductase class that catalyzes the reaction between catechol and oxygen to yield benzoquinone and water. It is a complex of copper-containing proteins that acts also on a variety of substituted catechols. EC 1.10.3.1.
The record of descent or ancestry, particularly of a particular condition or trait, indicating individual family members, their relationships, and their status with respect to the trait or condition.
Geological formations consisting of underground enclosures with access from the surface.
A heterogeneous group of bone dysplasias, the common character of which is stippling of the epiphyses in infancy. The group includes a severe autosomal recessive form (CHONDRODYSPLASIA PUNCTATA, RHIZOMELIC), an autosomal dominant form (Conradi-Hunermann syndrome), and a milder X-linked form. Metabolic defects associated with impaired peroxisomes are present only in the rhizomelic form.
Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.
Color of hair or fur.
The X-shaped structure formed by the meeting of the two optic nerves. At the optic chiasm the fibers from the medial part of each retina cross to project to the other side of the brain while the lateral retinal fibers continue on the same side. As a result each half of the brain receives information about the contralateral visual field from both eyes.
An area approximately 1.5 millimeters in diameter within the macula lutea where the retina thins out greatly because of the oblique shifting of all layers except the pigment epithelium layer. It includes the sloping walls of the fovea (clivus) and contains a few rods in its periphery. In its center (foveola) are the cones most adapted to yield high visual acuity, each cone being connected to only one ganglion cell. (Cline et al., Dictionary of Visual Science, 4th ed)
Glycoproteins found on the membrane or surface of cells.
Disorder characterized by a decrease or lack of platelet dense bodies in which the releasable pool of adenine nucleotides and 5HT are normally stored.

A republic in western Africa, south of SENEGAL and MALI, east of GUINEA-BISSAU. Its capital is Conakry.
Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.
Any of several generalized skin disorders characterized by dryness, roughness, and scaliness, due to hypertrophy of the stratum corneum epidermis. Most are genetic, but some are acquired, developing in association with other systemic disease or genetic syndrome.
A genetically heterogeneous disorder caused by hypothalamic GNRH deficiency and OLFACTORY NERVE defects. It is characterized by congenital HYPOGONADOTROPIC HYPOGONADISM and ANOSMIA, possibly with additional midline defects. It can be transmitted as an X-linked (GENETIC DISEASES, X-LINKED), an autosomal dominant, or an autosomal recessive trait.

An autosomal dominant disorder caused by deletion of the proximal long arm of the paternal chromosome 15 (15q11-q13) or by inheritance of both of the pair of chromosomes 15 from the mother (UNIPARENTAL DISOMY) which are imprinted (GENETIC IMPRINTING) and hence silenced. Clinical manifestations include MENTAL RETARDATION; MUSCULAR HYPOTONIA; HYPERPHAGIA; OBESITY; short stature; HYPOGONADISM; STRABISMUS; and HYPERSOMNOLENCE. (Menkes, Textbook of Child Neurology, 5th ed, p229)
An island in the Greater Antilles in the West Indies. Its capital is San Juan. It is a self-governing commonwealth in union with the United States. It was discovered by Columbus in 1493 but no colonization was attempted until 1508. It belonged to Spain until ceded to the United States in 1898. It became a commonwealth with autonomy in internal affairs in 1952. Columbus named the island San Juan for St. John's Day, the Monday he arrived, and the bay Puerto Rico, rich harbor. The island became Puerto Rico officially in 1932. (From Webster's New Geographical Dictionary, 1988, p987 & Room, Brewer's Dictionary of Names, 1992, p436)
A melanocortin receptor subtype found primarily in MELANOCYTES. It shows specificity for ALPHA-MSH and ADRENOCORTICOTROPIC HORMONE. Loss of function mutations of the type 1 melanocortin receptor account for the majority of red hair and fair skin recessive traits in human.
Chromatophores (large pigment cells of fish, amphibia, reptiles and many invertebrates) which contain melanin. Short term color changes are brought about by an active redistribution of the melanophores pigment containing organelles (MELANOSOMES). Mammals do not have melanophores; however they have retained smaller pigment cells known as MELANOCYTES.

Giant eyes in Xenopus laevis by overexpression of XOptx2. (1/186)

Overexpression of XOptx2, a homeodomain-containing transcription factor expressed in the Xenopus embryonic eye field, results in a dramatic increase in eye size. An XOptx2-Engrailed repressor gives a similar phenotype, while an XOptx2-VP16 activator reduces eye size. XOptx2 stimulates bromodeoxyuridine incorporation, and XOptx2-induced eye enlargement is dependent on cellular proliferation. Moreover, retinoblasts transfected with XOptx2 produce clones of cells approximately twice as large as control clones. Pax6, which does not increase eye size alone, acts synergistically with XOptx2. Our results suggest that XOptx2, in combination with other genes expressed in the eye field, is crucially involved in the proliferative state of retinoblasts and thereby the size of the eye.  (+info)

Induction of melanoma in TPras transgenic mice. (2/186)

In order to study the oncogenesis of melanocytes, transgenic mouse lines were established that express a mutated human Ha-ras (TPras) gene in pigment producing cells. The ras transgenic mice exhibit an altered phenotype, including melanocytic hyperplasia and a muted agouti coat, indicative of hyperproliferative melanocytes. These mice and their wild-type littermates have been subjected to a variety of carcinogenesis protocols, including 7, 12-dimethylbenz-[a]anthracene (DMBA), 12-O-tetradecanoylphorbol-13-acetate (TPA) and UV radiation exposure. Topical DMBA treatment of TPras mice resulted in a high incidence of melanomas. Metastatic lesions were observed in skin, lungs and lymph nodes. TPA treatment of TPras mice induced a small number of papillomas but no nevi or melanomas. UV light exposures induced papillomas in negative littermate and melanomas in some albino TPras mice. These results show that melanocytes expressing an activated Ha-ras in the TPras transgenic mice are susceptible to induction of melanoma by DMBA.  (+info)

Genetic disorders of vision revealed by a behavioral screen of 400 essential loci in zebrafish. (3/186)

We examined optokinetic and optomotor responses of 450 zebrafish mutants, which were isolated previously based on defects in organ formation, tissue patterning, pigmentation, axon guidance, or other visible phenotypes. These strains carry single point mutations in >400 essential loci. We asked which fraction of the mutants develop blindness or other types of impairments specific to the visual system. Twelve mutants failed to respond in either one or both of our assays. Subsequent histological and electroretinographic analysis revealed unique deficits at various stages of the visual pathway, including lens degeneration (bumper), melanin deficiency (sandy), lack of ganglion cells (lakritz), ipsilateral misrouting of axons (belladonna), optic-nerve disorganization (grumpy and sleepy), inner nuclear layer or outer plexiform layer malfunction (noir, dropje, and possibly steifftier), and disruption of retinotectal impulse activity (macho and blumenkohl). Surprisingly, mutants with abnormally large or small eyes or severe wiring defects frequently exhibit no discernible behavioral deficits. In addition, we identified 13 blind mutants that display outer-retina dystrophy, making this syndrome the single-most common cause of inherited blindness in zebrafish. Our screen showed that a significant fraction (approximately 5%) of the essential loci also participate in visual functions but did not reveal any systematic genetic linkage to particular morphological traits. The mutations uncovered by our behavioral assays provide distinct entry points for the study of visual pathways and set the stage for a genetic dissection of vertebrate vision.  (+info)

Extrinsic modulation of retinal ganglion cell projections: analysis of the albino mutation in pigmentation mosaic mice. (4/186)

Tyrosinase is a key enzyme involved in the synthesis of melanin in the retinal pigment epithelium (RPE). Mice that are homozygous for the albino allele at the tyrosinase locus have fewer retinal ganglion cells with uncrossed projections at the optic chiasm. To determine the site of the albino gene action we studied the projections of retinal ganglion cells in two types of pigmentation mosaic mice. First, we generated mosaic mice that contain a translocated allele of the wild-type tyrosinase on one X chromosome but that also have the lacZ reporter transgene on the opposite X chromosome. In these lacZ/tyrosinase mice, which are homozygous for the albino allele on chromosome 7, X-inactivation ensures that tyrosinase cannot be functional within 50% of the retinal ganglion cells and that these individual cells can be identified by their expression of the lacZ reporter gene product, beta-galactosidase. The proportion of uncrossed retinal ganglion cells expressing beta-galactosidase was found to be identical to the proportion that did not express it, indicating that the albino mutation associated with axonal behavior at the optic chiasm must affect ganglion cells in a cell-extrinsic manner. Second, to determine whether the RPE is the source of the extrinsic signal, we generated aggregation chimeras between pigmented and albino mice. In these mosaic mice, the extent of the uncrossed projection corresponded with the amount of pigmented cells within the RPE, but did not correspond with the genotypes of neural retinal cells. These studies demonstrate that the albino mutation acts indirectly upon retinal ganglion cells, which in turn respond by making axonal guidance errors at the optic chiasm.  (+info)

Genetically determined protein polymorphism in the rabbit nervous system. (5/186)

One of the polypeptides (H1) of the rabbit nervous system occurs in an altered form (H2) in some rabbits. The electrophoretic mobility of H2 on sodium dodecyl sulfate-polyacrylamide gels is about 6% greater than that of H1, suggesting that the two polypeptides differ in molecular weight by about 10,000. The alteration is genetically determined since (i) rabbit phenotypes corresponding to all possible genotypes (H1H1, H1H2, H2H2) were present in an outbred population of rabbits, (ii) the frequency of the phenotype corresponding to the heterozygous genotype (H1H2) was smaller in partially inbred rabbit populations than in outbred populations, and (iii) all of the individuals examined from two partially inbred strains (WH/J and X/J) were of the phenotype that would be expected if they were homozygous (H2H2) for the rare allele of the gene. Preliminary evidence indicates that this polymorphic polypeptide is most abundant in the white matter of the nervous systems of several mammalian species, and is distributed with buffers of low ionic strength and centrifuged at 100,000 Xg.  (+info)

arg-cys substitution at codon 1246 of the human myosin Va gene is not associated with Griscelli syndrome. (6/186)

Myosin Va is an actin-associated motor protein involved in organelle transport such as melanosomes and neuron synaptic vesicles and has always been proposed as the candidate gene for the autosomal recessive Griscelli-Prunieras syndrome, one of the silvery hair syndromes, which is a lethal disease combining immunodeficiency and neurologic and pigmentary abnormalities. Thus far, two mutations in the myosin Va gene have been described to be associated with this syndrome. One of these mutations was a homozygous mis-sense mutation causing an arginine to cysteine alteration at codon 1246. Because we also found this particular substitution after mutation analysis of a Griscelli patient, we checked its relevance in a control group of 124 unrelated healthy individuals and found it to be present, even in homozygous state, in normal unaffected individuals. It is clear that this arg1246cys substitution is a polymorphism occurring in the human population and not occurring in association with Griscelli syndrome. Distinguishing a polymorphism from a bona fide mutation is of utmost importance and has major ethical implications with regard to prenatal genetic counseling in affected families.  (+info)

X mapping in man: evidence against direct measurable linkage between ocular albinism and deutan colour blindness. (7/186)

Bile mediates intestinal pathology in endotoxemia in rats. (8/186)

Intestinal pathology frequently accompanies experimental endotoxic shock and is mediated by proinflammatory cytokines. Our hypotheses are that hepatobiliary factors operating from the luminal side of the gut make a major contribution to this damage and that tumor necrosis factor alpha (TNF-alpha) is involved in the pathology. We treated rats with lipopolysaccharide (LPS) intravenously and found that external drainage of bile totally protected the gastrointestinal tract, macroscopically and microscopically, 4 h after LPS administration and dramatically improved survival of the animals for 48 h after LPS administration. The concentration of TNF-alpha in bile increased markedly after LPS administration and was over 30 times higher in bile than in serum. Tissue damage and the biliary TNF-alpha response were abrogated when animals were pretreated with gadolinium chloride to eliminate Kupffer cells. TNF-alpha infusion into the duodenal lumen caused intestinal damage similar to that elicited by intravenous LPS. In rats treated with LPS, survival was significantly increased during the first 36 h in animals given an infusion of anti-TNF-alpha antibody into the duodenum. These results demonstrate that in endotoxemia, intestinal damage is mediated by factors derived from the bile. The findings indicate that luminally acting TNF-alpha contributes to the intestinal damage.  (+info)

Purpose: Preconditioning of albino mice using moderate intensity cyclic light may be confounded due to shortened photoreceptor outer segments and reduced rhodopsin expression such that the retinas are less sensitive to light. We hypothesize that preconditioning can be induced in pigmented mice with brief, sub-toxic light exposure. Here we describe the parameters used to induce such preconditioning.. Methods: Sixty-four male 129sv mice were obtained from Charles River (100 days old) and kept in a 12:12 light: dark cycle. Light-preconditioning was done using the following procedure: mice were treated with 1% atropine eye drops at 9:00AM and maintained in the dark for 1 hour to allow the pupils to dilate. Non-toxic light exposure consisted of 5k lux of white light for four hours using a LED lamp. Light-preconditioning was done either 1 or 3 days before LIRD. LIRD was done according to the following procedure: at 9:00AM mice were treated with 1% atropine eye drops and maintained in the dark for 1 ...

Albinism in humans is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes. Albinism is associated with a number of vision defects, such as photophobia, nystagmus, and amblyopia. Lack of skin pigmentation makes for more susceptibility to sunburn and skin cancers. In rare cases such as Chédiak-Higashi syndrome, albinism may be associated with deficiencies in the transportation of melanin granules. This also affects essential granules present in immune cells leading to increased susceptibility to infection. Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans. It is due to absence or defect of tyrosinase, a copper-containing enzyme involved in the production of melanin. It is the opposite of melanism. Unlike humans, other animals have multiple pigments and for these, albinism is considered to be a hereditary condition characterised by the absence of melanin in particular, in the ...

Rod and mixed rod-cone function was assessed by full field ERG following overnight dark adaptation. At baseline, BALB/c mice were characterized by lower b- and a-wave amplitudes as compared with C57Bl/6J age-matched mice (e.g., at the highest dark-adapted stimulus intensity of 10 cd*s/m2, mixed-rod cone b-wave amplitude was 436 ± 20 μV in BALB/c mice versus 609 ± 45 μV in C57Bl/6J and a-wave amplitude was 161 ± 8 μV versus 333 ± 30 μV; mean ± SEM, P , 0.00001, Fig. 2). Twenty-four hours following a single injection of 50 mg/kg of SI, rod-dominated ERG responses in BALB/c mice were reduced by more than 50% as compared to baseline. Dark-adapted responses in C57Bl/6J mice were better preserved. Moreover, b-wave amplitudes in C57Bl/6J mice were not statistically different from the baseline level at highest stimulus intensities. At this time point, cone-dominated responses in BALB/c were not different from the baseline at most stimulus intensities. Unexpectedly, C57Bl/6J mice showed ...

Albinism in children - What are the chances of a person with albinism passing his problem to their children? X-linked or recesiv. The transmission of albinism will depend on the form involved. A male may have an x-linked or autosomal recessive (ar) form. A female is most likely to have the recessive form. A male would not pass it to his sons but could pass the carrier state to his unaffected daughters who might pass it to her sons. The ar albino only passes a carrier state unless the spouse carries the ar gene.

Albinism consists of a group of inherited abnormalities of melanin synthesis and are typically characterized by a congenital reduction or absence of melanin pigment. Albinism results from defective production of melanin from tyrosine through a complex pathway of metabolic reactions.
Albinism Essay, Research Paper Albinism In the past, albinos were usually treated with fear or awe. They were sometimes killed at birth. Albino births were common enough in some groups not to cause any excitement. For example, among the San Blas Indians of Panama, one in approximately 130 births is an albino.
The past decade has brought news of an atrocity, mainly from Africa: the slaughter of humans with albinism for their body parts for use in ritual magic. Bodies are usually found headless and missing one or more limbs, but sometimes are completely torn apart, missing even internal organs. The reason is, of course, pure unadulterated pseudoscience; we can confidently state that there is no magical benefit to the use of unpigmented body parts, and thats to say nothing of the abhorrence of murder for any purpose. Clearly there are some fictional beliefs out there concerning the nature of people with albinism, and today were going to look at some more of these beliefs that might be held even by those of us who are not into black magic.. But the use of their body parts in ritual magic is the elephant in the room. Arms and legs are the witch doctors preferred bits. They are used as charms and talismans, and other body parts also have magical value, such as hair being sewn into fishing nets to bring ...

to keep up on current issues that may be related to my children.. Both children are mainstreamed into a public charter school so I was recently reviewing the Students with Albinism section of the Web site. I came upon the question that perked my interest: Does My Student Need Braille? The response on the Web site reads, Probably not. Most students with albinism have sufficient vision to use standard text, even if they need to use large print text or low vision aides. If your student with albinism is having difficulty reading print or tires of it easily, look into books on tape as an alternative.. I have to admit I was surprised at the belief and attitude NOAHs leadership has taken toward Braille. I feel that its one thing to take a position or give an opinion that most children with albinism will not need Braille (which I dont agree with), but the statement on your Web site could easily mislead parents about educational requirements.. The law clearly states that any visually impaired ...

People with this type of albinism have white or pink hair, skin, and iris color. They also have vision problems.. Another type of albinism, called ocular albinism type 1 (OA1), affects only the eyes. The persons skin and eye color are usually in the normal range. However, an eye exam will show that there is no coloring in the back of the eye (retina).. Hermansky-Pudlak syndrome (HPS) is a form of albinism caused by a change to a single gene. It can occur with a bleeding disorder, as well as with lung, kidney, and bowel diseases. ...
This tyrosinase-positive type of albinism is sometimes called rufous (ROCA) or brown (BOCA) oculocutaneous albinism and is frequently found in dark-skinned individual such as Africans, African-Americans, and Hispanics. Like other types it is inherited in an autosomal recessive pattern. Mutations in the tyrosinase-related protein-1, TYRP1 (9p23), are responsible which seems to lead to an arrest in melanin maturation and a decrease in the amount of insoluble melanin in melanocytes.. Other autosomal recessive types of oculocutaneous albinism are: OCA1 (203100, 606952), OCA2 (203200), and OCA4 (606574). ...
Oculocutaneous albinism (OCA) is a genetic disease characterized by the reduction or deficiency of melanin in eyes, skin, and hair. OCA exhibits genetic heterogeneity. Presently, there are four types
Abstract: Oculocutaneous albinism (OCA) is a genetically heterogeneous disorder. There are four known types of OCA: OCA1 OCA4. The clinical manifestations of all types of OCA include skin and hair hypopigmentation and visual impairment. Although there are a few documented observations of high frequency of albinism among Native Americans, including the Hopi, Zuni, Kuna, Jemez, Laguna, San Juan, and Navajo, no causative molecular defect has been previously reported. In the present study, we show that albinism in one Native American population, the Navajo, is caused by a LINE-mediated 122.5-kilobase deletion of the P gene, thus demonstrating that albinism in this population is OCA2. This deletion appears to be Navajo specific, because this allele was not detected in 34 other individuals with albinism who listed other Native American origins, nor has it been reported in any other ethnic group. The molecular characterization of this deletion allele allowed us to design a three-primer polymerase chain ...
Oculocutaneous albinism is a group of conditions that affect coloring (pigmentation) of the skin, hair, and eyes. Affected individuals typically have very fair skin and white or light-colored hair. Long-term sun exposure greatly increases the risk of skin damage and skin cancers, including an aggressive form of skin cancer called melanoma, in people with this condition. Oculocutaneous albinism also reduces pigmentation of the colored part of the eye (the iris) and the light-sensitive tissue at the back of the eye (the retina). People with this condition usually have vision problems such as reduced sharpness; rapid, involuntary eye movements (nystagmus); and increased sensitivity to light (photophobia).Researchers have identified multiple types of oculocutaneous albinism, which are distinguished by their specific skin, hair, and eye color changes and by their genetic cause. Oculocutaneous albinism type 1 is characterized by white hair, very pale skin, and light-colored irises. Type 2 is typically ...
CRISPR/Cas9 has become a powerful genome-editing tool for introducing genetic changes into crop species. In order to develop capacity for CRISPR/Cas9 technology in the tropical staple cassava (Manihot esculenta), the Phytoene desaturase (MePDS) gene was targeted in two cultivars using constructs carrying gRNAs targeting two sequences within MePDS exon 13. After Agrobacterium-mediated delivery of CRISPR/Cas9 reagents into cassava cells, both constructs induced visible albino phenotypes within cotyledon-stage somatic embryos regenerating on selection medium and the plants regenerated therefrom. A total of 58 (cv. 60444) and 25 (cv. TME 204) plant lines were recovered, of which 38 plant lines (19 from each cultivar) were analysed for mutagenesis. The frequency of plant lines showing albino phenotype was high, ranging from 90% to 100% in cv. TME 204. Observed albino phenotypes were comprised of full albinos devoid of green tissue and chimeras containing a mixture of white and green tissues. Sequence
Retinal axons undergo several changes in organization as they pass through the region of the optic chiasm and optic tract. We used immunocytochemistry to examine the possible involvement of fibroblast growth factor receptors (FGFR) in these changes in retinal axon growth. In the retina, at all ages examined, prominent staining for FGFR was seen in the optic fiber layer and at the optic disk. At embryonic day 15 (E15), FGFR immunoreactivity was also detected in the ganglion cell layer, as defined by immunoreactivity for islet-1. At later developmental stages (E16 to postnatal day 0), FGFR were found in the optic fiber layer and the inner plexiform layer. In the ventral diencephalon, immunostaining for FGFR was first detected at E13 in a group of cells posterior to the chiasm. These cells appeared to match the neurons that are immunopositive for the stage-specific embryonic antigen-1 (SSEA-1). FGFR staining was also found on the retinal axons at E13. At E14-E16, when most axons are growing across the

What is albinism? Albinism is an inherited condition. It affects the eyes and skin of some individuals, and only the eyes of others. It results from the bodys inability to produce normal amounts of a pigment called melanin.
Even though only about 5 mol% glycosphingolipids are found in cellular membranes, glycosphingolipids are essential during development, as a lack of these lipids was embryonically lethal in mice. A mutant cell line GM95 deficient in these lipids, was derived from the pigmented mouse melanoma cells MEB4. The first observation was ... read more that pigmentation is lost in the mutant glycosphingolipid-deficient GM95 cells. This was caused by mislocalisation of tyrosinase, the rate-limiting enzyme in pigment synthesis. We were able to locate the sorting signal in the lumenal domain of melanocytic proteins. Subsequently, we found that a lumenal determinant, pH, was less acidic in the TGN and lysosomes of mutant GM95 cells compared to the wild-type MEB4 cell line. Interestingly, the pH in both organelles of GM95 was comparable to HeLa cells and mouse fibroblasts. Therefore, it is the wild-type MEB4 cell line that has an abnormally low pH in its TGN and lysosomes. A similar low pH was found in a ...

The most frequent genetic basis for albinism in Africa is via homozygosity (often via culturally imbedded inbreeding) for an autosomal recessive variant of the gene OCA2 (oculocutaneous albinism type II), which encodes the P protein critically involved in pigmentation [8,102] (figure 1) and whose natural variants in Europeans are linked to skin cancer risk in GWAS [39,103]. Most African albinos have the same 2.7 kb deletion OCA2 mutation, indicative of a founder allele arising before the dispersion of ethnic subgroups throughout Africa 2000-3000 years ago [104]. The same mutation is commonly found in albinos in America of African or mixed African descent [105]. OCA2 type II, unlike type I, retains tyrosinase activity and therefore OCA2 albinos do synthesize pheomelanin (see figure 1) and have a variable capacity to develop pigmented patches or ephelides on exposed skin which may, as in normal white skin, provide some protection from UV damage and cancer [106,107]. Early studies showed that ...

Albinism is not just a flaw in appearance. The absence or reduction of the concentration of melanin in the structures of the eye violates the normal development of the ocular system. This leads to the formation of squinting albinos and progressive loss of vision. Conventional forms of strabismus are successfully treated by surgical methods, but with albinism, they have extremely low effectiveness.. Melanin protects us from the harmful effects of ultraviolet irradiation. Its absence eliminates skin and eye structure. Albinos are prone to sunburn. They have a significantly increased risk of developing skin cancer. Therefore, they have to be carefully protected with sunscreens and glasses.. Often, with albinism, adjacent genes are also affected, leading to the formation of various syndromes. So, with Chegiak-Higash syndrome there is a combination of albinism with congenital immunity decline. Angelas syndrome is accompanied by a decrease in mental development, microcephaly, hypotension and ...

What is albinism? For one thing, albinism is a recessive trait. That means both parents have to carry a certain gene. Do you know what a gene is? A gene is what makes you tall or short or gives you brown eyes or blue. If both of your parents are tall, they probably have genes to make them tall, and possibly passed that gene down to you. Well, back to recessive traits. A recessive trait is like a gene that doesn t show up very often. So, since albinism is a recessive trait, that means albinos are rare. And even if both parents carry the right gene(s), not all their offspring will be albino, only one in a few. That is another reason why albinos are so rare ...
People with albinism often experience social difficulties. As children they may be stared and pointed at and even teased and bullied, mostly due to ignorance. Since most people with albinism look vastly different from their families their sense of isolation is heightened.. They are also the subject of sympathetic looks and are treated as if they have severe disability or are dying of a horrible disease rather than a genetic condition that does not affect their minds.. The colour of skin has been a sensitive topic in all cultures throughout the ages. The issue is more heightened in people with albinism of African descent as they bear no resemblance to their race and their skin and hair resemble Caucasians. In many African societies, albino children were killed or abandoned at birth, or were denied breast milk and subjected to harsh conditions. They were even offered as ritual sacrifices. Albinos were thought of as cursed, a sign that punishment would befall the family. In Jamaica too, albinos ...

The distinction between genotype and phenotype is commonly experienced when studying family patterns for certain hereditary diseases or conditions, for example, hemophilia. Humans and most animals are diploid; thus there are two alleles for any given gene. These alleles can be the same (homozygous) or different (heterozygous), depending on the individual (see zygote). With a dominant allele, the offspring is guaranteed to inherit the trait in question irrespective of the second allele.. In the case of an albino with a recessive allele (aa), the phenotype depends upon the other allele (Aa, aA, aa or AA). An affected person mating with a heterozygous individual (Aa or aA, also carrier) there is a 50-50 chance the offspring will be albinos phenotype. If a heterozygote mates with another heterozygote, there is 75% chance passing the gene on and only a 25% chance that the gene will be displayed. A homozygous dominant (AA) individual has a normal phenotype and no risk of abnormal offspring. A ...

DRIPPING SPRINGS, Texas (KXAN) - Months after a rare pink grasshopper was found in a KXAN viewers garden, one of the insects rose-colored cousins has appeared on a viewers Dripping Springs porch!. It was just sitting on my porch, says Leah Burns, of Dripping Springs. I was able to come in and get my phone - and the little grasshopper didnt seem to mind me getting very close! I think it had had enough when I tried to pick it up and it jumped into the grass.. Now, you may be wondering: can grasshoppers really be pink?. And while they can be, they arent very common.. The pink coloration is a genetic mutation, Victoria Hillman with National Geographic says.. Hillman says the mutation is called erythrism, and its caused by a recessive gene similar to the one that affects albino animals. Its unusual and not very understood, she says, even though it was discovered in katydids in 1887. The mutation typically happens in the common meadow grasshopper, Hillman says.. Many pink grasshoppers dont ...

The story is about a sympathetic, even funny, protagonist with albinism, one attempt to counter the Evil Albino trope.

Luckily, each instruction booklet comes in two copies: one that was obtained from the animals mother, and one from its father.
