Aphalangy-hemivertebrae-urogenital-intestinal dysgenesis syndrome

MONDO:0008806

Aphalangy-hemivertebrae-urogenital-intestinal dysgenesis is an extremely rare congenital limb malformation syndrome, described in only 3 patients to date, and characterized by the association of hypoplasia or aplasia of the hand and foot phalanges, hemivertebrae and various urogenital and/or intestinal abnormalities (i.e. dysgenesis of the urogenital tract and rectum). There have been no further descriptions in the literature since 1991.

Background context

Johnson–Munson syndrome

Aphalangy, hemivertebrae and urogenital-intestinal dysgenesis or Johnson-Munson syndrome is an extremely rare syndrome, described only in three siblings. It associates hypoplasia or aplasia of phalanges of hands and feet, hemivertebrae and various urogenital and/or intestinal abnormalities. Intrafamilial variability is important as one sister had lethal abnormalities (Potter sequence and pulmonary hypoplasia), while her affected brother was in good health with normal psychomotor development at 6 months of age. Prognosis seems to depend mainly on the severity of visceral malformations. Etiology and inheritance remain unknown.
