ZSWIM2

Chr 2

zinc finger SWIM-type containing 2

Also known as: MEX, ZZZ2

The protein functions as an E3 ubiquitin-protein ligase that regulates Fas-, DR3- and DR4-mediated apoptosis by working with specific E2 ubiquitin-conjugating enzymes. Mutations cause autosomal recessive primary microcephaly, a neurodevelopmental disorder characterized by significantly reduced head circumference present from birth. The gene shows extreme intolerance to loss-of-function variants, indicating it is essential for normal human development.

The highest-scoring mechanism for this gene is gain-of-function.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
