TMSB4Y
Chr Ythymosin beta 4 Y-linked
Also known as: TB4Y
This gene encodes an actin-sequestering protein that binds actin monomers and inhibits actin polymerization, playing an important role in cytoskeletal organization. TMSB4Y is located in the male-specific region of the Y chromosome and has a homolog on the X chromosome that escapes X-inactivation. No established disease associations have been reported for mutations in this gene.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Tolerant to missense variation
The highest-scoring mechanism for this gene is gain-of-function.
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.
