MAPKAP1
Chr 9MAPK associated protein 1
Also known as: JC310, MIP1, SIN1, SIN1b, SIN1g
The protein functions as a component of the mechanistic target of rapamycin complex 2 (mTORC2), serving as a substrate adapter that recognizes and binds AGC protein kinase family members for phosphorylation by mTOR, thereby transducing growth factor signals to pathways controlling proliferation, cytoskeletal organization, and metabolism. Loss-of-function mutations in MAPKAP1 are predicted to cause disease through haploinsufficiency, as indicated by the extremely high pLI score (0.9999) and low LOEUF score (0.153), though specific neurogenetic disorders associated with this gene have not yet been characterized. The inheritance pattern and clinical phenotype remain to be defined as this represents an emerging disease gene.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Moderately missense-constrained (top ~2.5%)
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.
