ARL10
Chr 5ARF like GTPase 10
Also known as: ARL10A
ARL10 encodes a GTPase that binds GTP and localizes to mitochondria. Mutations cause autosomal recessive developmental and epileptic encephalopathy with movement abnormalities, typically presenting in infancy with seizures, developmental delay, and dystonia. The gene is not highly constrained against loss-of-function variants.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
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.
