RALA

Chr 7AD

RAS like proto-oncogene A

Also known as: HINCONS, RAL

RALA encodes a multifunctional GTPase that regulates cellular processes including gene expression, cell migration, exocytosis, and mitochondrial fission during cell division. Mutations cause Hiatt-Neu-Cooper neurodevelopmental syndrome with autosomal dominant inheritance. This gene is highly constrained against loss-of-function variants (pLI = 0.97, LOEUF = 0.27), indicating intolerance to functional disruption.

Definitive — sufficient evidence for diagnostic panels

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 0.97). One damaged copy is likely sufficient to cause disease.

This gene has evidence for multiple mechanisms of pathogenicity (loss-of-function and gain-of-function). Both the Badonyi & Marsh prediction and the broader genomic evidence point to loss-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

Literature Evidence

GOFThis study demonstrated for the first time that the somatic gain-of-function variant of RALA activates the mTOR pathway and leads to neuronal migration disorders in the brain, facilitating the development of FCD II.PMID:35846790

Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
