TAF1L
Chr 9TATA-box binding protein associated factor 1 like
Also known as: TAF(II)210, TAF2A2
The protein functions as a substitute for TAF1 during male meiosis when sex chromosomes are transcriptionally silenced, serving as a key transcriptional regulator in male germ cells. Mutations cause X-linked intellectual disability, and the gene shows high constraint against loss-of-function variants (pLI 0.96, LOEUF 0.32). The condition follows X-linked recessive inheritance.
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.
