SLX1B
Chr 16structure-specific endonuclease subunit SLX1B
Also known as: GIYD2
The protein functions as the catalytic subunit of the SLX1-SLX4 structure-specific endonuclease, which resolves DNA secondary structures and Holliday junctions during DNA repair and recombination processes. Pathogenic variants in SLX1B have not been definitively associated with human disease in the medical literature. The gene shows tolerance to loss-of-function variants (pLI = 0.04, LOEUF = 1.72), suggesting that complete loss of function may be compatible with normal development.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly tolerant — LoF variants common in population
Mild missense constraint
