EPHA6
Chr 3EPH receptor A6
Also known as: EHK-2, EHK2, EK12, EPA6, HEK12, PRO57066
EPHA6 encodes a receptor tyrosine kinase that binds ephrin-A ligands to mediate bidirectional cell signaling important for axon guidance and neural development. Mutations cause autosomal recessive spastic paraplegia and intellectual disability. The gene shows significant constraint against loss-of-function variants (LOEUF 0.357), indicating intolerance to disruption.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
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.
