Genes affected

USP27X (HGNC:13486): (ubiquitin specific peptidase 27 X-linked) This gene encodes a member of the peptidase protein family. The encoded protein functions as a deubiquitinase that is involved in upregulation of the pro-apoptotic Bim protein. This protein may act as a tumor suppressor by increasing levels of Bim to counteract anti-apoptotic signals in cancer cells. Mutations in this gene have been associated with X-linked cognitive disability. [provided by RefSeq, Dec 2016]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 4 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-49880701-G-T is Pathogenic according to our data. Variant chrX-49880701-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2499536.Status of the report is criteria_provided_single_submitter, 1 stars.
