Robinow mesomelic dysplasia is an autosomal dominant or recessive condition that results is a flat facial profile, mesomelic shortening and frequent genital hypoplasia. This report describes a case with bilateral deafness.
A boy was born at term to consanguineous parents who have no morphological abnormalities. The child's older brother and sister are normal. The patient was admitted at the age of 5 months because of abnormal features: enlarged skull with prominent forehead, flat facial profile, hypertelorism, small chin, shortening in the mesomelic segments of the limbs and genital hypoplasia without cryptorchidism. X-rays confirmed the mesomelic shortening and showed radial head dislocation and vertebral abnormalities. These abnormalities were more evident at the age of 2 1/2 years, when a bilateral sensorineural hearing loss was detected.
This case of Robinow has all the characteristic findings plus deafness. The parental consanguinity suggests that its inheritance is autosomal recessive.
