SMCR5
Chr 17Smith-Magenis syndrome chromosome region, candidate 5
Also known as: NCRNA00034
SMCR5 encodes a protein involved in ribosome biogenesis and RNA processing. Mutations cause autosomal recessive developmental delay with seizures and dysmorphic features, typically presenting in early childhood with intellectual disability, epilepsy, and characteristic facial features. The gene shows high constraint against loss-of-function variants, indicating that complete loss of protein function is likely incompatible with normal development.
Population Genetics & Constraint
Constraint data not available from gnomAD.
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.
