Y-2787320-C-T

Variant summary

Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1 PM5 PP3_Strong PP5

The NM_003140.3(SRY):c.284G>A(p.Gly95Glu) variant causes a missense change. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G95R) has been classified as Pathogenic.

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 9 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
• PM5: Other missense variant is known to change same aminoacid residue: Variant chrY-2787321-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 9750.Status of the report is no_assertion_criteria_provided, 0 stars.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.996
• PP5: Variant Y-2787320-C-T is Pathogenic according to our data. Variant chrY-2787320-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 9755.Status of the report is no_assertion_criteria_provided, 0 stars.
