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 13 ACMG points.

• PVS1: Start lost variant, no new inframe start found.
• PS1: Another start lost variant in NM_014009.4 (FOXP3) was described as [Pathogenic] in ClinVar as 1436074
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant X-49258503-C-T is Pathogenic according to our data. Variant chrX-49258503-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 11418.Status of the report is no_assertion_criteria_provided, 0 stars.
