The classical features of Kallmann syndrome with anosmia and hypogonadotropic hypogonadism were observed in two sisters aged 13 and 19. They had additional malformations including anosmia, bilateral vesico-ureteral reflux and unilateral hearing loss. One of the girls had unilateral coloboma of the optic nerve. The father had unilateral hearing loss and duplication of the left
ureter
; he died of an unrecognized coarctation of the aorta. He had no clinical signs of
hypogonadism
or anosmia. It is suggested that the malformations observed in these patients may be due to a dominant inherited defect of embryonic cell migration, resulting in different phenotypic expressions within the same family, including the Kallmann syndrome.

Two male fetuses (18 and 22 weeks gestation) and a 3-month-old male infant (full sibling of the younger fetus) who were diagnosed with Walker-Warburg syndrome (WWS) on the basis of neuropathologic autopsy findings in brain, eyes, and muscle also had micro-orchia and, microscopically, diffuse gonadoblastoid dysplasia in the testes. Both fetuses also had a miniature left
ureter
and cystic dysplastic left kidney. Testes from control fetuses of 17-24 weeks gestation with normal karyotype and no central nervous system abnormalities (group A, n = 50), a variety of central nervous system abnormalities (group B, n = 50), or an autosomal aneuploidy syndrome with or without central nervous system abnormalities (group C, n = 30) had no diffuse dysplasia, although a single gonadoblastoid seminiferous tubular profile was present in three controls. Testicular morphology was normal in older fetuses and infants with a wide variety of central nervous system malformations (group D, n = 50). We found no evidence of hypogonadotrophic
hypogonadism
in the three WWS cases to account for the small penis and incompletely descended testes commonly reported in this condition. We concluded that the apparent specificity of the gonadoblastoid testicular dysplasia to WWS suggests that the gene defect directly affects testicular development.
