Disorders:

Clinical Utility:

Genital ambiguity or discordant external genitalia

Notes:

This panel includes 19 genes; some variants in these genes may manifest
with genital ambiguity or external genitalia that are discordant with gender based on genetic
testing findings. Pathogenic variants in these genes may be suspected when the fetal karyotype
is 46,XY or non-invasive prenatal screening is consistent with the presence of a Y chromosome
but ultrasound reveals apparently female or ambiguous external genitalia. Ultrasound detection
of abnormalities of the genitalia can be detected as early as the 2nd trimester of pregnancy.
Depending on the underlying disorder, renal malformations, congenital heart defects,
limb/skeletal malformations, intrauterine growth restriction, cleft lip/cleft palate, and
congenital brain defects may also be observed by ultrasound. Note that some ultrasound
findings may not be detectable until the 3rd trimester of pregnancy. In addition, some disorders
may also present with abnormal findings on second trimester maternal serum screening, such as
abnormal maternal serum estriol (MS-uE3) levels.
