EMC2
Chr 8ER membrane protein complex subunit 2
Also known as: KIAA0103, TTC35
EMC2 encodes a component of the endoplasmic reticulum membrane protein complex (EMC) that facilitates the insertion of newly synthesized membrane proteins into ER membranes, particularly those with weakly hydrophobic transmembrane domains. Mutations cause a severe neurodevelopmental disorder with early infantile onset characterized by intellectual disability, developmental delay, seizures, and brain malformations. This condition follows an autosomal recessive inheritance pattern.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Typical tolerance to LoF variation
Mild missense constraint
The highest-scoring mechanism for this gene is dominant-negative.
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.
