Genes affected

FOXP3 (HGNC:6106): (forkhead box P3) The protein encoded by this gene is a member of the forkhead/winged-helix family of transcriptional regulators. Defects in this gene are the cause of immunodeficiency polyendocrinopathy, enteropathy, X-linked syndrome (IPEX), also known as X-linked autoimmunity-immunodeficiency syndrome. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-49255722-TC-T is Pathogenic according to our data. Variant chrX-49255722-TC-T is described in ClinVar as [Pathogenic]. Clinvar id is 211046.Status of the report is criteria_provided_single_submitter, 1 stars.
