Short rib-polydactyly syndrome, Verma-Naumoff type

Also known as: Short rib-polydactyly syndrome type 3



Short rib-polydactyly syndrome, Verma-Naumoff type is a short rib-polydactyly syndrome characterized by short limb dwarfism, short ribs with thoracic dysplasia, postaxial polydactyly and protuberant abdomen. Associated multiple malformations include cardiovascular defects, renal agenesis /hypoplasia, abnormal cloacal development (ambiguous genitalia, anal atresia) and cerebellar hypoplasia. Short rib-polydactyly syndrome, Verma-Naumoff type follows an autosomal recessive mode of transmission. The disease is usually fatal in the perinatal period.

Limb undergrowth limb shortening, Hypoplasia involving bones of the extremities, Short limb [more] Limb shortening because of underdevelopment of one or more bones of the extremities.
Ambiguous genitalia Ambiguous external genitalia, Intersex genitalia, Ambiguous external genitalia at birth [more] A genital phenotype that is not clearly assignable to a single gender. Ambiguous genitalia can be evaluated using the Prader scale: Prader 0: Normal female external genitalia. Prader 1: Female external genitalia with clitoromegaly. Prader 2: Clitoromegaly with partial labial fusion forming a funnel-shaped urogenital sinus. Prader 3: Increased phallic enlargement. Complete labioscrotal fusion forming a urogenital sinus with a single opening. Prader 4: Complete scrotal fusion with urogenital opening at the base or on the shaft of the phallus. Prader 5: Normal male external genitalia. The diagnosis of ambiguous genitalia is made for Prader 1-4.
Postaxial polydactyly Postaxial hexadactyly A form of polydactyly in which the extra digit or digits are localized on the side of the fifth finger or fifth toe.
