IllnessPrenatal DSD

NGS +

[Sanger]

DSD are rarely present prenatally, very complex conditions, management should be directed by highly specialised teams to allow consideration of all aspects of diagnosis, treatment + ethical issues. Female fetus (clitoromegaly with normal labia). Male fetus (micropenis, hypospadias, undescended testes, bifid scrotum). Associated abnormalities: Chromosomal, mainly trisomy 13, triploidy, 13q syndrome, in a few cases. The condition is commonly associated with genetic syndromes (Smith-Lemli-Opitz + WAGR syndromes), other defects, mainly facial clefts + cardiac defects are often found.
