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 7 ACMG points.

• PM1: In a helix (size 15) in uniprot entity SRY_HUMAN there are 4 pathogenic changes around while only 0 benign (100%) in NM_003140.3
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.993
• PP5: Variant Y-2787267-C-T is Pathogenic according to our data. Variant chrY-2787267-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 9744.Status of the report is no_assertion_criteria_provided, 0 stars.
