Update on a family with hand-foot-genital syndrome: hypospadias and urinary tract abnormalities in two boys from the fourth generation.

We describe a fourth generation of involvement with hand-foot-genital syndrome. The first 3 generations of this family, which included 5 affected females and no affected males, were reported previously by Verp et al. [1983]. In the fourth generation, 2 affected males are identified. To our knowledge, the findings of bilateral vesicoureteral reflux in one boy and bilateral ureteropelvic junction obstruction in his cousin represent the first reports of urinary tract abnormalities in males with this syndrome.
