TSC22D1
Chr 13TSC22 domain family member 1
Also known as: HUCEP-2, Ptg-2, TGFB1I4, TSC22
This gene encodes a leucine zipper transcription factor that represses transcription of multiple genes including C-type natriuretic peptide and regulates TGF-beta signaling pathways involved in apoptosis and tumor suppression. The gene is highly constrained against loss-of-function variants (pLI 0.96, LOEUF 0.33), but no established Mendelian disease associations have been reported in the provided data. A promoter polymorphism has been associated with diabetic nephropathy susceptibility.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
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.
