A single gene defect leads to differing degrees of renal and hepatic involvement, with very different phenotypes and clinical outcome within even one affected family. [2] Kidneys are bilaterally enlarged and contain large numbers of cysts throughout the organ, due to the dilatation and elongation of renal collecting ducts. At birth, the interstitium and the rest of the tubules are normal but th...

ellis-van creveld syndrome is a very rare autosomal recessive skeletal dysplasia characterized by a short stature, short limbs, short ribs, postaxial polydactyly, dysplastic nails, multiple frenula, and congenital heart defects.  we describe a 22-year-old boy with a short stature, short limbs, short distal extremities, small teeth, short upper lip bound by frenula to the alveolar ridge, multipl...

BACKGROUND Congenital microphthalmia (OMIM: 309700) may occur in isolation or in association with a variety of systemic malformations. Isolated microphthalmia may be inherited as an autosomal dominant, an autosomal recessive, or an X linked trait. METHODS Based on a whole genome linkage analysis, in a six generation consanguineous family with autosomal recessive inheritance, the first locus f...

First cousins, a male and a female, with a new type of hidrotic ectodermal dysplasia are described. They were each the result of first cousin marriage from the Egyptian Karaite community. They both had partial adontia, conical peg-shaped teeth, fine hair that did not grow long, normal sweating, eversion of lips, and pronounced facial similarity. The male had cleft lip on the right side while th...

Sickle cell disease is an autosomal recessive hematological disorder resulting from a missense point mutation in the beta chain of haemoglobin molecule. This article reports case homozygous sickle adult patient with long-standing history non-healing ulcer

Fifteen forms of limb-girdle muscular dystrophies (5 autosomal dominant and 10 autosomal recessive) have already been found. The 10 genes responsible for the autosomal recessive forms, which account for more than 90% of the cases, had their product identified. This review will focus on the most recent data on autosomal recessive-limb-girdle muscular dystrophy and on our own experience of more t...

Two brothers with congenital conductive hearing loss and phenotypic characteristics of maxillofacial dysostosis are described. In the oldest boy a malformed ossicular chain was present and the conductive hearing loss was improved by a malleo-vestibulo-pexy, with post-operative hearing gain of approximately 30 dB. Although superficially similar to Treacher Collins syndrome, the facial characteri...

Segregation analysis on 228 family pedigrees collected from a Papua New Guinean population provided data that strongly supported a previous report of an autosomal recessive pattern of inheritance of a susceptibility to tinea imbricata. The frequency of the susceptibility gene within the population studied was found to be 0.49 +/- 0.04, calculated on the assumption of an autosomal recessive mode...
