SUBMICROSCOPIC DUPLICATION OF 8q24.3 REGION IS A POTENTIAL CANDIDATE FOR DISORDERS OF SEX DEVELOPMENT

Abstract

Submicroscopic duplication of 8q24.3 region is a potential candidate for disorders of sex development: Some of the disorders of sex development (DSD), including 46, XX testicular DSD formerly called "XX maleness" and 46, XY DSD with partial or complete gonadal dysgenesis primarily affect the gonads. Genetic alterations in ten unrelated females with complete 46, XY gonadal dysgenesis (GD) were analyzed using an Array 2.7 M platform with whole genome coverage. The analysis result suggested that the most significant region maps to chromosome 8q24.3 which were previously reported by another independent study with a similar patient cohort and this region being probable candidate related to complete 46, XY GD.
