CLDN34
Chr Xclaudin 34
The protein functions in tight junction formation by mediating calcium-independent cell adhesion and obliterating intercellular spaces between cells. The gene is not highly constrained against loss-of-function variation, and no established human diseases have been definitively linked to CLDN34 mutations in the current literature.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
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.
