Buschke-Ollendorff syndrome (BOS; MIM 166700) or osteopoikilosis (OPK) is an autosomal dominant connective tissue disorder caused by mutations in the LEMD3 gene. BOS is characterized by multiple, nontender and firm cutaneous nevi or nodules. The cutaneous nevi may be elastin rich or collagen rich. OPK is defined as spotted bone, consisting of multiple hyperostotic foci of old remolded bone. OPK may occur in isolation, or it can occur in combination with the elastin or collagen rich cutaneous nodules. The combination of OPK and cutaneous nodules or nevi is considered as BOS. Variable expression may occur in families. Some family members may have both skin and bone lesions while others may lack one or the other findings. LEMD3 encodes the LEM domain-containing protein 3, an integral protein of the inner nuclear membrane. This molecule is thought to antagonize bone morphogenetic protein and transforming growth factor -β signaling through interactions with Smad family proteins. LEMD3 loss of ...

Osteopetrosis (marble bone disease) is a descriptive term that refers to a group of rare, heritable disorders of the skeleton characterized by increased bone density on radiographs. The overall incidence of these conditions is difficult to estimate but autosomal recessive osteopetrosis (ARO) has an incidence of 1 in 250,000 births, and autosomal dominant osteopetrosis (ADO) has an incidence of 1 in 20,000 births. Osteopetrotic conditions vary greatly in their presentation and severity, ranging from neonatal onset with life-threatening complications such as bone marrow failure (e.g. classic or malignant ARO), to the incidental finding of osteopetrosis on radiographs (e.g. osteopoikilosis). Classic ARO is characterised by fractures, short stature, compressive neuropathies, hypocalcaemia with attendant tetanic seizures, and life-threatening pancytopaenia. The presence of primary neurodegeneration, mental retardation, skin and immune system involvement, or renal tubular acidosis may point to rarer

In a 55-year-old man with an 8 year history of intermittent knee osteoarthritis (OA), deep venous thrombosis (DVT) was diagnosed in his right lower leg. There was no history of risk factors for thrombosis, such as prolonged bed rest or long air travel. On physical examination there were signs of DVT in the right lower leg and OA of the knees with a small amount of intraarticular fluid; and a large Bakers cyst originating from the right knee joint was suspected. Ultrasonography showed multiple hyperechogenic loose bodies in a Bakers cyst (Figure 1).. On radiographic examination, multiple round or ovoid… ...

Osteomesopyknosis is a rare autosomal dominant condition characterized by osteosclerosis of the axial skeleton. Its radiological abnormalities consist of increased density of the vertebral plates, pelvis, and sometimes of the upper part of the femurs. It is usually discovered incidentally on radiographic examination, is a mild form of familial osteosclerosis and must be distinguished from osteopetrosis which carries a worse prognosis. A marked increase uptake may be found on bone scintigraphy. Microscopic examination of bone shows an increase of trabecular thickness, and a low rate of bone turnover.

Primordial dwarfism (PD) is a form of dwarfism that results in a smaller body size in all stages of life beginning from before birth.[1] More specifically, primordial dwarfism is a diagnostic category including specific types of profoundly proportionate dwarfism, in which individuals are extremely small for their age, even as a fetus. Most individuals with primordial dwarfism are not diagnosed until they are about 3-5 years of age.. Medical professionals typically diagnose the fetus as being small for gestational age, or as having intrauterine growth disability when an ultrasound is conducted. Typically, people with primordial dwarfism are born with very low birth weights. After birth, growth continues at a much slower rate, leaving individuals with primordial dwarfism perpetually years behind their peers in stature and in weight.. Most cases of short stature are caused by skeletal or endocrine disorders. The five subtypes of primordial dwarfism are among the most severe forms of the 200 types ...

Primordial Dwarfism Definition It is a type of dwarfism that leads to a smaller body stature at all stages during the life of a person, beginning from birth. It is a rare and acute form of dwarfism. Primordial Dwarfism History This condition was first noted in 1815 in a baby girl born in Italy. This girl was Caroline

Interstitial deletions of 3q29 have been recently described as a microdeletion syndrome mediated by nonallelic homologous recombination between low-copy repeats resulting in an ~1.6 Mb common-sized deletion. Given the molecular mechanism causing the deletion, the reciprocal duplication is anticipated to occur with equal frequency, although only one family with this duplication has been reported. In this study we describe 14 individuals with microdeletions of 3q29, including one family with a mildly affected mother and two affected children, identified among 14,698 individuals with idiopathic mental retardation who were analyzed by array CGH. Eleven individuals had typical 1.6-Mb deletions. Three individuals had deletions that flank, span, or partially overlap the commonly deleted region. Although the clinical presentations of individuals with typical-sized deletions varied, several features were present in multiple individuals, including mental retardation and microcephaly. We also identified 19

Background: The chromosome 17q21.31 microdeletion syndrome is a novel genomic disorder that has originally been identified using high resolution genome analyses in patients with unexplained mental retardation. Aim: We report the molecular and/or clinical characterisation of 22 individuals with the 17q21.31 microdeletion syndrome. Results: We estimate the prevalence of the syndrome to be 1 in 16 000 and show that it is highly underdiagnosed. Extensive clinical examination reveals that developmental delay, hypotonia, facial dysmorphisms including a long face, a tubular or pear-shaped nose and a bulbous nasal tip, and a friendly/amiable behaviour are the most characteristic features. Other clinically important features include epilepsy, heart defects and kidney/urologic anomalies. Using high resolution oligonucleotide arrays we narrow the 17q21.31 critical region to a 424 kb genomic segment (007: 41046729-41470954, hg17) encompassing at least six genes, among which is the gene encoding microtubule

The 2p15p16.1 microdeletion syndrome has a core phenotype consisting of intellectual disability, microcephaly, hypotonia, delayed growth, common craniofacial features, and digital anomalies. So far, more than 20 cases of 2p15p16.1 microdeletion syndrome have been reported in the literature; however, the size of the deletions and their breakpoints vary, making it difficult to identify the candidate genes. Recent reports pointed to 4 genes (XPO1, USP34, BCL11A, and REL) that were included, alone or in combination, in the smallest deletions causing the syndrome. Here, we describe 8 new patients with the 2p15p16.1 deletion and review all published cases to date. We demonstrate functional deficits for the above 4 candidate genes using patients lymphoblast cell lines (LCLs) and knockdown of their orthologs in zebrafish. All genes were dosage sensitive on the basis of reduced protein expression in LCLs. In addition, deletion of XPO1, a nuclear exporter, cosegregated with nuclear accumulation of one of ...

When youre first given the news that your child has been pre-diagnosed or diagnosed with Primordial Dwarfism along with the different life threatening medical issues they may face, your emotions can be very mixed and extreme. Parents encounter the feelings of isolation, anxiety, sadness, despair, guilt and anger mixed up with an overwhelming love and protectiveness.. This is common situation with many parents when their child is born or later diagnosed with a disability or find themselves in a position when one of their children, another family member or even themselves are diagnosed with a life threatening condition.. Due to the rarity of Primordial Dwarfism and its sub-types, parents feel frustrated due to the lack of information at the time of the initial pre-diagnosis or formal diagnosis, more so as they are referred from one specialist to another, desperately seeking to understand what is going one with their child.. One thing that we want to try to ensure and explain to you is that you ...

Meier-Gorlin syndrome (MGS) is a rare autosomal recessive disorder characterized by primordial dwarfism, microtia, and patellar aplasia/hypoplasia. Recently, mutations in the ORC1, ORC4, ORC6, CDT1, and CDC6 genes, encoding components of the pre-replication complex, have been identified. This complex is essential for DNA replication and therefore mutations are expected to impair cell proliferation and consequently could globally reduce growth. However, detailed growth characteristics of MGS patients have not been reported, and so this is addressed here through study of 45 MGS patients, the largest cohort worldwide. Here, we report that growth velocity (length) is impaired in MGS during pregnancy and first year of life, but, thereafter, height increases in paralleled normal reference centiles, resulting in a mean adult height of -4.5 standard deviations (SD). Height is dependent on ethnic background and underlying molecular cause, with ORC1 and ORC4 mutations causing more severe short stature and ...

Multiple exostoses is a condition in which people develop multiple abnormal bone growths on the surface of a pre-existing bone. The number and locations of the exostoses varies greatly among individuals with the condition. Affected individuals usually do not have exostoses at birth, but develop them by the time they are around twelve years of age. The growth of exostoses usually stops when an individual reaches physical maturity and the bones stop growing. Multiple exostoses can cause stunted growth, uneven limb lengths, and other skeletal abnormalities. They can often be painful and affect movement. Although exostoses are usually benign, they may become cancerous in some instances. Multiple exostoses may be treated by surgically removing the growths ...

The inner nuclear membrane proteins emerin and LEMD2 have both overlapping and separate functions in regulation of nuclear organization, gene expression and cell differentiation. We report here that emerin/EMR-1 and LEMD2/LEM-2 are expressed in all tissues throughout Caenorhaditis elegans development but their relative distribution differs between cell types. The ratio between EMR-1 and LEM-2 is particularly high in contractile tissues, intermediate in neurons and hypodermis and lowest in intestine and germ line. We find that LEM-2 is recruited earlier than EMR-1 to reforming nuclear envelopes, suggesting the presence of separate mitotic membrane compartments and specific functions of each protein. Concordantly, we observe that nuclei of lem-2 mutant embryos, but not of emr-1 mutants, have reduced nuclear circularity. Finally, we uncover a novel role of LEM-2 in nuclear separation and anchoring of microtubule organizing centers.. ...

In 1997, Drake Taylor, 3, was one of fewer than 200 people in the world diagnosed with Majewski osteodysplastic primordial dwarfism type II. Unlike achondroplasia, the most common type of dwarfism, Drakes limbs and other features were proportional. But he was shockingly smaller in stature - only about two feet tall and 11 pounds - than other children his age. And his high-pitched, squeaky voice always attracted attention. This didnt stop him from expressing his energetic personality and charming everyone around him. In 2012, at the age of 18, Drake succumbed to Moyamoya disease, a narrowing of blood vessels at the base of the brain that restricts blood flow and leads to aneurysms. He was fully grown at 39 inches tall and 39 pounds.. ...
