Ellis Van Creveld (EVC) syndrome is one of the congenital anomalies not compatible with life. It is also known as chondroectodermal dysplasia. The most common manifestations of this syndrome are short ribs, postaxial polydactyly, growth retardation, and ectodermal and cardiac defects. It has an incidence of one in every 60,000 live births and equal sex predisposition. In our case, perinatal aut...

McKusick-Kaufman syndrome is a rare syndrome inherited in an autosomal recessive pattern with a phenotypic triad comprising hydrometrocolpos, postaxial polydactyly and congenital cardiac disease. The syndrome is caused by mutations in the MKKS gene mapped onto chromosome 20p12. Diagnosis of this syndrome is based on clinical and imaging findings. In our paper, we have presented the first McKusi...

We prove more special cases of the Fontaine-Mazur conjecture regarding p-adic Galois representations unramified at p, and we present evidence for and consequences of a generalization of it.

A change in susceptibility to tumor transplantation with the use of two sarcomas is reported in this paper to have arisen concomitantly with the sudden reversal in the penetrance of polydactylism in mouse//46801 of the Strong Polydactylous strain. Mice of the subline derived from #46801 grew the tumors in only 68 and 78 per cent of the cases, whereas the same subline without the polydactylism r...

We report two fetuses with hydrocephalus, features of holoprosencephaly, and postaxial polydactyly born to a consanguineous Mexican-American couple. The phenotype is consistent with the hydrolethalus syndrome, although holoprosencephaly has not previously been seen in this condition. We believe other similar cases with a trisomy 13 phenotype but normal chromosomes may also have the hydrolethalu...

Megalencephaly, polymicrogyria, polydactyly, and hydrocephalus (MPPH) syndrome has been recently recognized and is very rare. Each case reported so far has demonstrated hydrocephalus to varying degrees. We report an infant with MPPH syndrome, but lacking frank hydrocephalus. The additional finding of an abnormally elongated pituitary infundibulum has not been described in this syndrome and, alo...

The short rib polydactyly syndromes (SRPSs) are a heterogeneous group of autosomal recessive, perinatal lethal skeletal disorders characterized primarily by short, horizontal ribs, short limbs and polydactyly. Mutations in several genes affecting intraflagellar transport (IFT) cause SRPS but they do not account for all cases. Here we identify an additional SRPS gene and further unravel the func...

Werner mesomelia is characterized by a sequence variation in the specific region (position 404) of the enhancer ZRS of SHH. The phenotype comprises variable mesomelia, abnormalities of the thumb and great toe and supernumerary digits. We describe extensive variation in limb phenotype in a large family and report on a novel sequence variation NG_009240.1: g.106737G>T (traditional nomenclature: Z...
