Also known as: A15, CCG-B7, CD231, DXS1692E, MRX58, MXS1, TALLA-1, TM4SF2
The protein is a cell surface glycoprotein that regulates neurite outgrowth and complexes with integrins to mediate signal transduction events controlling cell development, activation, growth and motility. Mutations cause X-linked intellectual developmental disorder with onset in early childhood. The gene shows moderate constraint against loss-of-function variants (pLI 0.75, LOEUF 0.54) and follows X-linked recessive inheritance.
Primary Disease Associations & Inheritance
Moderate evidence — consider for supplementary testing
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.
