MARF1
Chr 16meiosis regulator and mRNA stability factor 1
Also known as: KIAA0430, LKAP, LMKB, PPP1R34
MARF1 encodes an essential regulator of oogenesis that represses transposable elements and protects against DNA double-strand breaks during female meiotic progression. Mutations cause primary ovarian insufficiency with autosomal recessive inheritance. This gene is highly constrained against loss-of-function variants, indicating mutations are likely to have significant clinical consequences.
Population Genetics & Constraint
gnomAD v4 — loss-of-function & missense intolerance
Among the most LoF-intolerant genes (~top 3%)
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.
