limb girdle muscular dystrophies (lgmds) are group of neuromuscular disorders which are characterized by progressive muscle weakness and they mostly affect the pelvic and shoulder girdle muscles. this disease can be inherited as autosomal dominant (lgmd1) and autosomal recessive (lgmd2). so far seven autosomal dominant and 20 autosomal recessive forms of this disease have been recognized reflec...

Woolly hair is an uncommon congenital anomaly of the scalp presenting with strongly coiled involving a localized area or covering entire side and occurring in non-black people. Among syndromes woolly hair, most known are Naxos syndrome, Carvajal-Huerta hair/hypotrichosis, ectodermal dysplasia-skin fragility tricho-hepato-enteric syndrome. Case characteristics: herein, we report case autosomal r...

Thalassemia is a preventable hereditary disorder,each of the parent must be autosomal recessive tohave child with serious symptoms majordisease. occurs due to abnormal ordeficient Hemoglobin (an iron containing proteins)in Red Blood cells. Depending upon type ofproteins involved, there are two types ofThalassemia, aThalassemia and (3 12

We screened 526 unrelated patients with autosomal dominant, autosomal recessive, or simplex retinitis pigmentosa for evidence of mutations of the genes encoding S-antigen (S-Ag), interstitial retinol binding protein (IRBP), and the alpha-subunit of cone-specific transducin. Restriction fragment length polymorphisms (RFLPs) were identified at each of these loci. Within each set of patients with ...

PURPOSE Some 30% of cases of congenital cataract are genetic in origin, usually transmitted as an autosomal dominant trait. The molecular defects underlying some of these autosomal dominant cases have been identified and were demonstrated to be mostly mutations in crystallin genes. The autosomal recessive form of the disease is less frequent. To date, only four genes and three loci have been as...

We report herein on our observation of recessive congenital methemoglobinemia (type I), an autosomal recessive disorder, in immediate generations (in a mother and her daughter). Molecular analysis revealed a mechanism of inheritance not reported previously, despite the high probability of occurrence in autosomal recessive disorders. This report is also the first publication describing an extrem...

Autosomal dominant (Thomsen) and recessive (Becker) congenital myotonia are two different non dystrophic disorders, due to allelic mutations of the muscle chloride channel gene, located on chromosome 7q35. More than two thirds of the muscle chloride channel gene mutations occur independently in unique families and cause the recessive form of the disease. Becker disease is more common and severe...

schimke immuno-osseous dysplasia is a rare autosomal recessive multisystem disorder characterized by steroid-resistant nephrotic syndrome, immunodeficiency, and spondyloepiphy-seal dysplasia. mutations in swi/snf2 related, matrix associated, actin dependent regulator of chromatin, subfamily a-like 1 (smarcal1) gene are responsible for the disease. the present report describes, for the first tim...

Limb-girdle muscular dystrophies (LGMD) are a highly heterogeneous group of muscle disorders, which first affect the voluntary muscles of the hip and shoulder areas. The definition is highly descriptive and less ambiguous by exclusion: non-Xlinked, non-FSH, non-myotonic, non-distal, nonsyndromic, and non-congenital. At present, the genetic classification is becoming too complex, since the acron...
