SRRM2
Chr 16ADserine/arginine repetitive matrix 2
Also known as: 300-KD, CWF21, Cwc21, HSPC075, MRD72, SRL300, SRm300
The protein is required for pre-mRNA splicing as a component of both major and minor spliceosomes, participating in the removal of introns from pre-mRNAs. Mutations cause intellectual developmental disorder, autosomal dominant 72, following an autosomal dominant inheritance pattern. The gene is highly constrained against loss-of-function mutations (pLI ~1.0, LOEUF 0.118), indicating that functional copies are essential for normal development.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Among the most LoF-intolerant genes (~top 3%)
Tolerant to missense variation
The highest-scoring mechanism for this gene is loss-of-function (haploinsufficiency).
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
