ERICH3
Chr 1glutamate rich 3
Also known as: C1orf173
ERICH3 encodes a protein that controls primary cilium formation and length, and is also involved in neuronal vesicle biogenesis and neurotransmitter vesicular function. Mutations cause autosomal recessive neurodevelopmental disorders with intellectual disability, seizures, and movement abnormalities. The gene shows tolerance to loss-of-function variation, consistent with a recessive inheritance pattern affecting ciliary and neuronal functions.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.
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.
