We report a six year old male with mental retardation, postaxial polydactyly and syndactyly, atrichia congenita totalis, severe seborrhoeic dermatitis, recurrent staphylococcal skin sepsis, and Perthes' disease of the hip. His birth may have resulted from an incestuous mating.

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 The etiology of birth defects has been widely studied but is not yet fully clarified, previously published data had suggested that maternal age or parity maybe involved, but without consistent conclusions. METHODS A population-based, case-control study was nested in a cohort of perinatal infants born from 2010 to 2012 in Baoan District, Shenzhen. Four categories of isolated birth d...

Bardet-Biedl syndrome (BBS) is an autosomal recessive condition characterised by rod-cone dystrophy, postaxial polydactyly, central obesity, mental retardation, hypogonadism, and renal dysfunction. BBS expression varies both within and between families and diagnosis is often difficult. We sought to define the condition more clearly by studying 109 BBS patients and their families, the largest po...

Short rib-polydactyly syndrome (SRPS) is a group of rare, lethal skeletal dysplasias characterized by short ribs and limbs, polydactyly, hypoplastic thorax and visceral anomalies. Our case had coarsening of facial features, low-set ears, lobulated tongue, cleft palate, and hypoplastic epiglottis. Short proximal parts of upper limbs, bilateral postaxial polydactyly of hands, and bifid big toe wi...
