RIMKLB
Chr 12ribosomal modification protein rimK like family member B
Also known as: FAM80B, NAAGS, NAAGS-I
The protein catalyzes the synthesis of beta-citryl-L-glutamate and N-acetyl-L-aspartyl-L-glutamate in the cytoplasm. Mutations cause autosomal recessive intellectual disability with seizures and hypotonia, typically presenting in infancy or early childhood. This gene is highly constrained against loss-of-function variants, indicating intolerance to protein disruption.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Moderately missense-constrained (top ~2.5%)
