A characteristic symptom complex.

Congenital duplication of the lens. (1/187)

A case of reduplication of the lens with uveal coloboma is described. This is a rare condition and, unlike the two previously reported cases, the other ocular structures and adnexae appeared normal.  (+info)

Clinical characteristics of CHARGE syndrome. (2/187)

CHARGE syndrome, first described by Pagon, was named for its six major clinical features. They are: coloboma of the eye, heart defects, atresia of the choanae, retarded growth and development including CNS anomalies, genital hypoplasia and/or urinary tract anomalies, and ear anomalies and/or hearing loss. We experienced three cases of CHARGE syndrome who displayed ocular coloboma, heart defects, retarded growth and development, and external ear anomalies, and we also review the previously reported literature concerning CHARGE syndrome.  (+info)

Looking behind a pathological blind spot in human retina. (3/187)

Recent work suggests that dichoptic lateral interactions occur in the region of the visual field of one eye that corresponds to the physiological blind spot in the other eye (Tripathy, S. P., & Levi, D. M. (1994). The two-dimensional shape of spatial interaction zones in the parafovea. Vision Research, 34, 1127-1138.) Here we ask whether dichoptic lateral interactions occur in the region of the visual field of one eye that corresponds to a pathological blind spot, a retinal coloboma in the other eye. To address this question we had the observer report the orientation of a letter 'T' presented within this region in the presence of flanking 'T's presented to the other eye around the coloboma. A large drop in performance was seen due to the flanks, showing the existence of dichoptic lateral interactions in this monocular region. The presence of these dichoptic interactions in a region lacking direct retinal afferents from one eye is consistent with the proposition that long-range horizontal connections of the primary visual cortex mediate these interactions.  (+info)

Demonstration of exclusive cilioretinal vascular system supplying the retina in man: vacant discs. (4/187)

PURPOSE: To report the fluorescein angiographic and Doppler ultrasonographic findings in a patient with apparent exclusive ciliary vascular supply of the retina of both eyes. METHODS: Case report. RESULTS: The ophthalmoscopic appearance of all arterial vessels emanating from both discs was consistent with a cilioretinal origin. Retinal veins also entered each disc peripherally near the margin, leaving the central part of each disc vacant. Fluorescein angiography showed filling of all arterial vessels simultaneous with the early-phase choroidal background flush bilaterally. Color and power Doppler ultrasonographic imaging demonstrated unequivocally the absence of central retinal vessels within the optic nerves. Both discs were normal in size and excavated with central glial tissue present. The clinical history of monocular, alternating episodes of failing vision with partial resolution and the retinal pigmentation patterns bilaterally were consistent with, though not conclusive for, previous episodes of serous retinal detachments. Coincident systemic anomalies consisted of small kidneys with reduced renal parenchyma discovered on ultrasonography, along with chronic interstitial nephritis. CONCLUSIONS: The ophthalmoscopic appearance of optic discs with apparent all-cilioretinal vascular supply has been reported previously, but proof of the absence of central retinal vessels requires Doppler ultrasonographic evidence corroborated by angiographic findings, as exemplified in our case report. We describe the association of this disc anomaly with renal parenchymal disease and its distinction from colobomatous defects.  (+info)

Dysgenesis of the internal carotid artery associated with transsphenoidal encephalocele: a neural crest syndrome? (5/187)

We describe two original cases of internal carotid artery dysgenesis associated with a malformative spectrum, which includes transsphenoidal encephalocele, optic nerve coloboma, hypopituitarism, and hypertelorism. Cephalic neural crest cells migrate to various regions in the head and neck where they contribute to the development of structures as diverse as the anterior skull base, the walls of the craniofacial arteries, the forebrain, and the face. Data suggest that the link between these rare malformations is abnormal neural crest development.  (+info)

Pax2 in development and renal disease. (6/187)

Pax genes are associated with a variety of developmental mutations in mouse and man that are gene dosage sensitive, or haploinsufficient. The Pax2 gene encodes a DNA binding, transcription factor whose expression is essential for the development of the renal epithelium. Both gain and loss of function mutants in the mouse demonstrate a requirement for Pax2 in the conversion of metanephric mesenchymal precursor cells to the fully differentiated tubular epithelium of the nephron. However, Pax2 expression is down-regulated as cells leave the mitotic cycle. Humans carrying a single Pax2 mutant allele exhibit renal hypoplasia, vesicoureteric reflux, and optic nerve colobomas. Conversely, persistent expression of Pax2 has been demonstrated in a variety of cystic and dysplastic renal diseases and correlates with continued proliferation of renal epithelial cells. Thus, Pax2 misexpresssion may be a key determinant in the initiation and progression of renal diseases marked by increased or deregulated cell proliferation.  (+info)

Bitemporal pseudohemianopia related to the "tilted disk" syndrome: CT, MR, and fundoscopic findings. (7/187)

We describe a case of the "tilted-disk" syndrome in a patient with a bitemporal field depression (a pseudohemianopia). CT and MR imaging showed thinning and prolapse of the nasal sectors of the posterior walls of the globes and flattening of the temporal portion of the globes.  (+info)

The homeodomain protein vax1 is required for axon guidance and major tract formation in the developing forebrain. (8/187)

The homeodomain protein Vax1 is expressed in a highly circumscribed set of cells at the ventral anterior midline of the embryonic CNS. These cells populate the choroid fissure of the optic disk, the body of the optic stalk and nerve, the optic chiasm and ventral diencephalon, and the anterior midline zones that abut developing commissural tracts. We have generated mutant mice that lack Vax1. In these mice (1) the optic disks fail to close, leading to coloboma and loss of the eye-nerve boundary; (2) optic nerve glia fail to associate with and appear to repulse ingrowing retinal axons, resulting in a fascicle of axons that are completely segregated from optic nerve astrocytes; (3) retinal axons fail to penetrate the brain in significant numbers and fail to form an optic chiasm; and (4) axons in multiple commissural tracts of the anterior CNS, including the corpus callosum and the hippocampal and anterior commissures, fail to cross the midline. These axon guidance defects do not result from the death of normally Vax1(+) midline cells but, instead, correlate with markedly diminished expression of attractive guidance cues in these cells. Vax1 therefore regulates the guidance properties of a set of anterior midline cells that orchestrate axon trajectories in the developing mammalian forebrain.  (+info)

Ocular coloboma combined with cleft lip and palate: a case report | BMC Ophthalmology | Full TextOcular coloboma combined with cleft lip and palate: a case report | BMC Ophthalmology | Full Text
Ocular coloboma is an excavation of ocular structures that occurs due to abnormal fusion of the embryonic optic fissure. Further, cleft lip/palate (CL/P), a congenital midline abnormality, is caused by a defect in the fusion of the frontonasal, maxillary, and mandibular prominences. No study has reported the association between these two phenotypes in the absence of other systemic abnormalities. We present a case of ocular coloboma along with CL/P and without other neurological abnormalities. A 5-year-old Asian boy presented with decreased visual acuity in his right eye. Physical examination revealed no abnormal findings except CL/P, which was surgically corrected at the age of 9 months. Best-corrected visual acuity was 20/60 in the right eye and 20/25 in the left eye. Anterior segment examination revealed iris coloboma in the inferior quadrant of his right eye as well as a large inferonasal optic disc and chorioretinal coloboma in the same eye. He was prescribed glasses based on his cycloplegic

Ocular coloboma: a reassessment in the age of molecular neuroscience. - Oxford Neuroscience
Congenital colobomata of the eye are important causes of childhood visual impairment and blindness. Ocular coloboma can be seen in isolation and in an impressive number of multisystem syndromes, where the eye phenotype is often seen in association with severe neurological or craniofacial anomalies or other systemic developmental defects. Several studies have shown that, in addition to inheritance, environmental influences may be causative factors. Through work to identify genes underlying inherited coloboma, significant inroads are being made into understanding the molecular events controlling closure of the optic fissure. In general, severity of disease can be linked to the temporal expression of the gene, but this is modified by factors such as tissue specificity of gene expression and genetic redundancy.

Optic disc duplication or coloboma? | British Journal of OphthalmologyOptic disc duplication or coloboma? | British Journal of Ophthalmology
Typical colobomas are located inferiorly and slightly nasally, resulting from failure of closure of the fetal fissure. The fetal fissure closes first in the region of the equator, with progressive closure anteriorly and posteriorly from that point. Failure of the fetal fissure to close posteriorly results in absence of choroid, pigment epithelium, and retina in that area.2 The choroidal net seems to develop wherever mesoderm is in contact with pigmented epithelium. The choroid appears pari passu with the retinal pigment, and closure of the fetal fissure is not always constant.3 Case 3 demonstrates a chorioretinal coloboma positioned superior to the optic disc (fig 1C). Donoso et al1 have demonstrated such a lesion linked to the true optic disc with retinal vessels. An alternative more plausible hypothesis is that an inflammatory focus caused such a peripapillary chorioretinal coloboma.. We demonstrate a double blind spot by Humphrey automated visual field testing (fig 2A). Two distinct blind ...

Coloboma is an ocular birth defect resulting from abnormal development of the eye during embryogenesis. It is defined as a congenital defect in any ocular tissue, typically presenting as absent tissue or a gap, at a site consistent with aberrant closure of the optic fissure. Failure of fusion can lead to coloboma of one or multiple regions of the inferior portion of the eye affecting any part of the globe traversed by the fissure, from the iris to the optic nerve, including the ciliary body, retina, and choroid. Coloboma is also frequently associated with small (microphthalmic) or absent (anophthalmic) eyes as part of an interrelated spectrum of developmental eye anomalies, and can affect either one or both eyes (summary by Kelberman et al., 2014).

Renal coloboma syndrome (RCS) is an autosomal dominant disorder caused by PAX2 gene mutations and characterized by renal hypoplasia and optic disc coloboma. The clinical findings were retrospectively reviewed, and all coding regions of the PAX2 gene were sequenced, in six children with RCS. A c.619_620insG mutation was detected in five patients, including two siblings, and a novel p.Arg104X mutation was detected in one patient. All the patients had progressive renal dysfunction and bilateral hypoplastic kidneys without vesicoureteral reflux (VUR), but the rate of progression to end-stage renal disease showed some diversity. The ocular manifestations showed wide variability, ranging from subtle optic disc anomalies to microphthalmia. In one family with two affected siblings, maternal germline mosaicism was suggested by an intragenic microsatellite marker study. In conclusion, there are variable renal and ocular manifestations in RCS without significant phenotype-genotype correlations. VUR is not ...

Uveal coloboma: about 3 cases at the University Teaching Hospital, Yaounde, CameroonUveal coloboma: about 3 cases at the University Teaching Hospital, Yaounde, Cameroon
Uveal coloboma is a rare eye malformation caused by failure of the optic fissure to close during the fifth to seventh weeks of foetal life. The risk of retinal detachment increases with age in colobomatous eyes. Preventive measures such as early detection of the retinal break , prophylactic laser photocoagulation along the coloboma margin, confer a significant benefit in reducing this risk of retinal detachment. Difficulties linked to the diagnosis and management of uveal colobomas in developing countries setting are presented in this study.

Purpose : To Study the outcomes for management of retinal detachment in eyes with chorioretinal colobomas. Methods : A multicenter retrospective review of 119 patients with chorioretinal colobomas who underwent surgery for rhegmatogenous retinal detachment. Patients with a retinal break or a hole within the normal retinal tissue and retinal detachment not involving the coloboma were excluded. Depending on the intraoperative situation, additional procedures performed during pars plana vitrectomy (PPV) included pars plana lensectomy (PPL), epiretinal membrane (ERM) peeling, and use of encircling band. This was followed by fluid-air exchange, gas tamponade with 25% sulfur hexafluoride or 15% octafluoropropane, or silicone oil injection. Results : 119 eyes of 119 consecutive patients (83; 69.7% male and 36; 29.3% female) with a mean (±SD) age of 20.3 (±11.6) years were identified.

Defining the Sequence Elements and Candidate Genes for the Coloboma MutationDefining the Sequence Elements and Candidate Genes for the Coloboma Mutation
The chicken coloboma mutation exhibits features similar to human congenital developmental malformations such as ocular coloboma, cleft-palate, dwarfism, and polydactyly. The coloboma-associated region and encoded genes were investigated using advanced genomic, genetic, and gene expression technologies. Initially, the mutation was linked to a 990 kb region encoding 11 genes; the application of the genetic and genomic tools led to a reduction of the linked region to 176 kb and the elimination of 7 genes. Furthermore, bioinformatics analyses of capture array-next generation sequence data identified genetic elements including SNPs, insertions, deletions, gaps, chromosomal rearrangements, and miRNA binding sites within the introgressed causative region relative to the reference genome sequence. Coloboma-specific variants within exons, UTRs, and splice sites were studied for their contribution to the mutant phenotype. Our compiled results suggest three genes for future studies.

The eye derives from three embryologic germ layers. Neuroectoderm gives rise to the optic vesicle; neural crest cells are responsible for migration to the anterior chamber of the developing eye. Ectoderm is responsible for the formation of the lens placode. Neuroectodermal and mesodermal cells participate in the closure of the optic fissure. The variety of cells and tissue types involved explains variability of phenotypic abnormalities of the eye (see Table 29-1) (Warburg, 1993). The embryonic optic fissure is formed from invagination along the inferior aspect of the optic cup and optic stalk at the 5-to-8-mm stage of gestation. This fissure allows the ingress of the hyaloid artery and egress of retinal axons through the optic nerve. In the normal eye, the embryonic optic fissure closes at 33 to 44 days after conception. If the fissure fails to fuse, a defect in the neuroectodermal and uveal tissues will be produced, forming a coloboma. The coloboma is a layer of sclera lined by maldeveloped ...

CHARGE is a rare condition that can affect different parts of the body. The most common problems are with the eyes, ears, heart, nasal passages, feeding and growth - although the condition, and its severity, does vary from person to person.. The name CHARGE was first used in 1981 to refer to a newly recognised cluster of features seen in a number of children. Over the years, it has become clear that CHARGE is a Syndrome and at least one gene causing CHARGE Syndrome has been discovered. The letters in CHARGE were originally used to describe some of the typical features of the syndrome as follows:. Coloboma of the eye, (This is an eye deformity where part of the eye has failed to develop properly and is missing) Heart Defects, Atresia of the choanae, (This is a closure of one, or both, of the openings at the back of the nose.) Delay of growth and/or development, Genital and/or urinary abnormalities, and Ear Abnormalities and deafness. It estimated that 4 - 6% of the deafblind population are ...

An exploration of the role of MAB21l1 in MAC-Spectrum Anomalies | IOVS | ARVO JournalsAn exploration of the role of MAB21l1 in MAC-Spectrum Anomalies | IOVS | ARVO Journals
Purpose : Microphthalmia, anophthalmia and coloboma (MAC spectrum) are structural ocular disorders that are sources of childhood blindness. These disorders are highly genetically heterogeneous; however, many cases remain without genetic diagnoses. Mutations in MAB21L2 have been previously associated with MAC phenotypes in human patients and confirmed in zebrafish model. This study tested the hypothesis that MAB21L family member, MAB21L1, may also participate in ocular development and contribute to disorders. Methods : We examined 276 human patients with developmental ocular conditions, including MAC spectrum anomalies. Samples were screened by Sanger Sequencing of full-length MAB21L1 coding region. To further study MAB21L1, we utilized zebrafish model to analyze expression and function in development. To do so, we carried out in situ hybridization of 18-72 hpf wild-type embryos using a mab21l1 probe. We also generated mab21l1-deficient lines using TALENs. Results : Human samples revealed one ...

Research into MACS conditions - MACSResearch into MACS conditions - MACS
MACS conditions are likely to be caused by a disruption in the way the eye develops in the baby during early pregnancy. This can be due to an alteration in an important gene for eye development, environmental factors - such as drugs or infection in pregnancy - or a combination of the these things. However, while some families have been given a genetic diagnosis, others are no closer to knowing why their child has been affected by MACS and its related conditions.. MACS is supporting the work of specialist eye consultant and geneticist Professor Nicola Ragge, who has been responsible for the discovery of many genes linked to Microphthalmia, Anophthalmia and Coloboma. We are contributing towards the costs of a part-time Family Co-ordinator based at Oxford Brookes University who is responsible for recruiting and liaising with families involved in the research and keeping them up to date on progress and findings in relation to their specific cases..

SALL2, also known as Spalt-like transcription factor 2, is a member of the SALL family of transcription factors involved in development and conserved through evolution. Since its identification in 1996, findings indicate that SALL2 plays a role in neurogenesis, neuronal differentiation and eye development. Consistently, SALL2 deficiency associates with neural tube defects and coloboma, a congenital eye disease. Relevant to cancer, clinical studies indicate that SALL2 is deregulated in various ca

Brooks Group - National Human Genome Research Institute (NHGRI)Brooks Group - National Human Genome Research Institute (NHGRI)
Dr. Brooks studies a potentially blinding congenital malformation of the eye called uveal coloboma. The condition is caused by failure of the optic fissure to close during the fifth week of human gestation. Although the embryology leading to coloboma has been well-characterized for decades, less is known about the genetic and developmental processes responsible for this condition, making genetic counseling and molecular diagnosis difficult. The Brooks laboratory integrates clinical and genetic data from uveal coloboma patients with molecular, developmental, and biochemical studies of normal and faulty optic fissure closure in model systems. The ultimate goal of the research is to apply knowledge from clinical and laboratory studies to molecular diagnosis in families with coloboma and to devise prevention and treatment strategies. Dr. Brooks applies Mendelian and complex genetics approaches to studying uveal coloboma in patients. His laboratory has identified a unique syndrome in which abnormal ...

Malformations.org - View a combination
Description: CHARGE syndrome was initially defined as a non-random association of anomalies (Coloboma, Heart defect, Atresia choanae, Retarded growth and development, Genital hypoplasia, Ear anomalies/deafness). In 1998, an expert group defined the major (the classical 4Cs: Choanal atresia, Coloboma, Characteristic ears and Cranial nerve anomalies) and minor criteria of CHARGE syndrome. Individuals with all four major characteristics or three major and three minor characteristics are highly likely to have CHARGE syndrome. In 2004 a Netherlands study (Vissers, LELM, et.al) found a gene (CHD7 on 8Q12) which was implicated in 2/3 of those tested. This gene is responsible for encoding a number of DNA protein which is esential when neural crest cells are being formed and migrating. A negative genetic test for changes in the CHD7 gene can still result in a diagnosis of CHARGE ...

Choanal Atresia RepairChoanal Atresia Repair
Choanal atresia describes the congenital narrowing of the back of the nasal cavity that causes difficulty breathing in neonate. Choanal atresia is often associated with CHARGE, Treacher Collins and Tessier Syndrome. It is a rare condition that occurs in 1:7000 live births, seen in females twice as often as males, and affects bilaterally in roughly 50% of cases. Bilateral choanal atresia is usually repaired in the newborn period. Unilateral CA repair is often deferred until age 2-3 years. Stent placement has become optional as stentless repair is gaining popularity because this technique decreases foreign body reaction in the nasopharynx which in term decreases granulation formation. Transnasal endoscopic choanal atresia repair is performed by opening the atresia bilaterally, drilling out pterygoid bone as needed, and removal of the posterior septum and vomer. Normal mucosa is preserved as much as possible by elevating a lateral based mucosal flap to prevent scarring and restenosis. Postoperatively,

Choanal atresia - WikipediaChoanal atresia - Wikipedia
Choanal atresia is a congenital disorder where the back of the nasal passage (choana) is blocked, usually by abnormal bony or soft tissue (membranous) due to failed recanalization of the nasal fossae during fetal development. It can be unilateral or bilateral. Sometimes, a unilateral choanal atresia is not detected until much later in life because the baby manages to get along with only one nostril available for breathing. Bilateral choanal atresia is a very serious life-threatening condition because the baby will then be unable to breathe directly after birth as babies are obligate nasal breathers (they mainly use their noses to breathe). In some cases, this may present as cyanosis while the baby is feeding, because the oral air passages are blocked by the tongue, further restricting the airway. The cyanosis may improve when the baby cries, as the oral airway is used at this time. These babies may require airway resuscitation soon after birth. Sometimes babies born with choanal atresia also ...

Joubert Syndrome 16 - CAGSJoubert Syndrome 16 - CAGS
Joubert syndrome (JS) is an inherited multi-visceral disorder caused by aberrant primary cilia formation and function. JS is characterized by the Molar Tooth Sign (MTS), a mid-hindbrain malformation easily identifiable through an axial brain MRI scan. Neurological features include hypotonia, ataxia, and cognitive impairment. The clinical phenotype additionally includes retinal, renal, hepatic -and more rarely- orofacial, skeletal, cardiac, genital, and endocrinal defects. JS is thought to affect 1 in 100,000 births; however the incidence in consanguineous populations is thought to be much higher (e.g. ~1 in 5000 for UAE).. JS16 (JBTS16) is a subtype of JS very similar to JBTS2, involving characteristic neurological features with mainly ocular involvement; renal, skeletal (polydactyly), and genital (cryptorchidism) defects are additional albeit relatively rarely reported features. The ocular phenotype involves retinal dystrophy, oculomotor apraxia, reduced visual acuity, as well as chorioretinal ...

Hyaloid Vasculature and mmp2 Activity Play a Role during Optic Fissure by Megan L. Weaver, Warlen P. Piedade et al.Hyaloid Vasculature and mmp2 Activity Play a Role during Optic Fissure by Megan L. Weaver, Warlen P. Piedade et al.
Vertebrate retinal development requires timely and precise fusion of the optic fissure (OF). Failure of this event leads to congenital vision impairment in the form of coloboma. Recent studies have suggested hyaloid vasculature to be involved in OF fusion. In order to examine this link, we analyzed OF fusion and hyaloid vasculogenesis in the zebrafish pax2a noi mutant line. We first determined that pax2a−/− embryos fail to accumulate F-actin in the OF prior to basement membrane (BM) degradation. Furthermore, using 3D and live imaging we observed reduced OF hyaloid vascularization in pax2a−/− embryos. When examining the connection between pax2a loss of function and hyaloid vasculature, we observed significant reduction of talin1 expression, a regulator of hyaloid vasculature. In addition, cranial VEGF expression was found to be reduced in pax2a−/− embryos. Pharmacological inhibition of VEGF signaling phenocopied the pax2a−/− vasculature, F-actin and BM degradation phenotypes. Lastly, we

Joubert syndrome is an autosomal - recessive developmental disorder with an incidence of approximately 1:100 000. It is characterized by cerebellar vermis hypoplasia, cerebellar ataxia, muscular hypotension, oculomotor apraxia, neonatal respiratory distress, mental retardation as well as retinal degeneration. It is therefore also described as cerebello-oculo-renal syndrome. Additionally Joubert syndrome can be associated with hepatic fibrosis, ocular coloboma and polydactyly. There is a high phenotypic variability even within families. The unifying pathognomonic sign is a cerebellar vermis hypoplasia presenting in MRI as the so called molar tooth sign.. Approximately 25% of patients with JS present with NPH depending on the underlying genetic defect. At the moment mutations in 22 genes are known to cause JS of witch AHI1, RPGRIP1L and CC2DA2 are the most frequently affected accounting for 10% of JS cases each..

Molecular Vision: Mutational screening of six genes in Chinese patients with congenital cataract and microcorneaMolecular Vision: Mutational screening of six genes in Chinese patients with congenital cataract and microcornea
In this study, we screened 6 genes for mutations in 9 Chinese families with congenital cataract and microcornea. Three mutations were identified in 3 of the 9 (30%) families, including a c.34C,T (p.Arg12Cys) in CRYAA, and a c.136G,A (p.Gly46Arg) and a c.116C,G (p.Thr39Arg) in GJA8, respectively. CRYAA is located in 21q22.3 and encodes the α-A-crystallin in lens epithelial cells and fiber cells. α-A-crystallin is a member of small heat shock proteins with the chaperone activity which contributes to keeping lens transparent [6,10,27]. Up to now, there were eight mutations of CRYAA found in sixteen families most of which involved substitutions from or to arginine [5]. And the corresponding phenotypes of the mutations were related with congenital cataract with or without microcornea, microphthalmia, or iris coloboma. We found a known c.34C,T (p.Arg12Cys) mutation in CRYAA of three patients from a family with congenital nuclear cataract and microcornea. Previously, this mutation has been identified ...

Interventional Cardiology | Swedish Medical Center Seattle and Issaquah
Swedish pioneered the PFO treatment, which involves using a special device - a tiny, double-umbrella apparatus - to seal a small congenital defect in the heart known as a patent foramen ovale (PFO). A PFO results from incomplete closure after birth in the atrial septum, which is a thin wall separating the upper chambers of the heart. It has been implicated as a potential cause for unexplained strokes in young adults. Repairing the defect may therefore reduce the patients future stroke risk.. Like PFO, an atrial septum defect (ASD) results from incomplete closure after birth in the wall between the left and right atria. About 7 percent of congenital heart defects fall into this category, and if the defect is large enough, oxygen-rich blood from the left atrium flows back into the right side of the heart and is pumped back to the lungs instead of to the rest of the body. This results in more work for the heart. Patients with large ASDs experience shortness of breath with physical exertion. ...

Karyotype of the baby was suggestive of Trisomy 13. Trisomy 13 or Patau syndrome was first observed by Erasmus Bartholin in 1657 but the chromosomal nature of the disease was ascertained by Klaus Patau in 1960. Incidence is seen more among females. {1} The frequency of this syndrome is 1:10000-15000 live births. {2} Median survival is fewer than 3 days. It is due to a non-disjunction of chromosomes during meiosis. Some are caused by Robertsonian translocations. The risk of this syndrome in the offspring increases with maternal age at pregnancy with about 31years being the average. {3} The presence of holoprosencephaly may cause early death {4}. Eighty-five percent do not survive beyond one year of life and most die before completing six months. {4} Patau syndrome is characterized by the following triad : microphthalmia, cleft lip and palate and polydactyly.

The reported incidence of CHARGE Syndrome ranges from 0.1 to 1.2/10,000 and depends primarily on professional recognition. It is not known to be related to any illness, exposure to drugs or alcohol intake during pregnancy, and typically it does not occur to more than one person in a family. It is very rare, and cannot be predicted. Coloboma mainly affects the retina. Major and minor congenital heart defects (commonest cyanotic heart defect is tetralogy of Fallot) occur in 75 80% of patients. Choanal atresia may be membranous or bony, bilateral or unilateral, and is present in 50 60 percent of cases. Mental retardation (ranging from minimal to profound retardation) is another common feature. Under-development of external genitalia is a common finding in males but is less apparent in females.

Life is unpredictable and a world is naturally shaken up a bit when a baby is born. We had expected to experience some measure of unpredictability with our first child. However, when our daughter, Zoe, was born in the Fall of 2003 we knew our lives were going to change in a way we had never prepared. In some ways prenatal screening had prepared us for the physical differences in our child born with a significant cleft lip and palate. We did our research and knew the surgeries she would need would be extensive along with the feeding obstacles and we were ready for that challenge.

CHARGE association is a non-random collection of congenital anomalies. The condition is becoming more widely known to medical and educational professionals. The number of children diagnosed is increasing, probably because of the greater awareness of this condition. This paper considers some of the long-term management problems which are often deferred in the early months, when acute life threatening problems take priority. Questionnaires were sent to parents via the CHARGE Association Family Support Group, UK. Thirty-nine were returned and incomplete information was sought by personal contact or telephone. The majority of children were known professionally to one or both authors and information was therefore checked from medical and educational notes. There is still widespread misunderstanding about the impact of multiple disability, especially when this includes multi-sensory impairment, on the early development of the child. Therefore, the information collected from the study has been from an ...
