Genes affected

SRY (HGNC:11311): (sex determining region Y) This intronless gene encodes a transcription factor that is a member of the high mobility group (HMG)-box family of DNA-binding proteins. This protein is the testis-determining factor (TDF), which initiates male sex determination. Mutations in this gene give rise to XY females with gonadal dysgenesis (Swyer syndrome); translocation of part of the Y chromosome containing this gene to the X chromosome causes XX male syndrome.

XGY2 (HGNC:34022): (XG Y-linked 2 (pseudogene))

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM1: In a hotspot region, there are 3 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 2 uncertain in NM_003140.3
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.881
• PP5: Variant Y-2787299-G-A is Pathogenic according to our data. Variant chrY-2787299-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2506477.Status of the report is criteria_provided_single_submitter, 1 stars.
