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

Our verdict: Likely_pathogenic. The variant received 8 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
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 19 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: -0.13831 (below the threshold of 3.09). Trascript score misZ: NaN (below the threshold of 3.09). GenCC associations: The gene is linked to 46,XX sex reversal 1, 46,XY sex reversal 1, 46,XY partial gonadal dysgenesis, 46,XX ovotesticular disorder of sex development, 46,XY complete gonadal dysgenesis.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.986
• PP5: Variant Y-2787207-G-A is Pathogenic according to our data. Variant chrY-2787207-G-A is described in ClinVar as Pathogenic. ClinVar VariationId is 9752.Status of the report is no_assertion_criteria_provided, 0 stars.
