TFDP1
Chr 13transcription factor Dp-1
Also known as: DILC, DP1, DRTF1, Dp-1
The protein encoded by this gene heterodimerizes with E2F transcription factors to regulate genes involved in cell cycle progression from G1 to S phase and DNA replication. Mutations cause intellectual disability, microcephaly, and growth retardation with autosomal dominant inheritance. This gene is highly constrained against loss-of-function variants (pLI 0.97, LOEUF 0.32), indicating intolerance to protein-disrupting mutations.
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.
