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 Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a mutagenesis_site Reduces nuclear localization. Strongly reduces nuclear localization; when associated with G-62. Reduces interaction with KPNB1. Does not reduce interaction with CAML. Does not abolish DNA-binding. (size 0) in uniprot entity SRY_HUMAN
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.931
