CYP11B2
Chr 8ARcytochrome P450 family 11 subfamily B member 2
This enzyme catalyzes the biosynthesis of aldosterone, the primary mineralocorticoid responsible for salt and water homeostasis and blood pressure regulation. Mutations cause autosomal recessive congenital hypoaldosteronism (corticosterone methyl oxidase deficiency types I and II), presenting with salt wasting, dehydration, and failure to thrive in infancy. The gene shows tolerance to loss-of-function variants (LOEUF 1.572), consistent with the recessive inheritance pattern where both alleles must be affected to cause disease.

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 dominant-negative.
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.
