TSHZ2
Chr 20teashirt zinc finger homeobox 2
Also known as: C20orf17, OVC10-2, TSH2, ZABC2, ZNF218
TSHZ2 encodes a transcriptional repressor containing zinc fingers and a homeobox DNA-binding domain that regulates developmental processes. Mutations cause autosomal dominant developmental delays, intellectual disability, and congenital anomalies including heart defects and genitourinary malformations. This gene is highly constrained against loss-of-function variants, indicating that even single functional copies are critical for normal development.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Highly LoF-intolerant (top ~10% of genes)
Mild missense constraint
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.
