SREBF1
Chr 17ADsterol regulatory element binding transcription factor 1
Also known as: HMD, IFAP2, SREBP1, bHLHd1
The protein is a transcription factor that regulates genes involved in cholesterol biosynthesis and lipid homeostasis, becoming activated when sterol concentrations are low. Mutations cause ichthyosis with follicular atrichia and photophobia syndrome as well as mucoepithelial dysplasia, inherited in an autosomal dominant pattern. The gene shows moderate constraint against loss-of-function variants (LOEUF 0.45), and the associated conditions primarily affect skin and mucosal tissues.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
More LoF-intolerant than ~75% of genes
Mild missense constraint
The Badonyi & Marsh model scores dominant-negative highest, but genomic evidence most strongly supports loss-of-function (haploinsufficiency) as the primary mechanism.
Literature Evidence
Predictions from Badonyi M, Marsh JA. PLoS ONE. 2024;19(8):e0307312. Mechanism ranking also informed by gnomAD constraint, ClinVar, and ClinGen data.
