Gonadal Mosaicism of Frasier Syndrome in 3 Chinese Siblings With Donor Splice Site Mutation of Wilms' Tumour Gene

Nephron. 2002 Jul;91(3):526-9. doi: 10.1159/000064302.


Frasier syndrome is a rare human developmental disorder classically affecting 46,XY females and leading to male pseudohermaphroditism and chronic renal failure. We describe a family with both 46,XX and 46,XY females affected by the syndrome due to WT1 splice site mutations. The diagnosis of Frasier syndrome in 1 of the children led to the discovery of the syndrome in 2 other siblings, of whom 1 is asymptomatic. Since the mutation was not found in either parents, gonadal mosaicism was suggested. The implication of family screening for WT1 gene mutation in asymptomatic members is also discussed.
