Added comment: i) PMID: 23902945- heterozygous stop gained p. Ser429X variant in 6 POI-affected women segregated in a large family; mRNA in white blood cells from 3 affected women demonstrated nonsense mutant transcript at a decreased proportion compared with that in gDNA, suggesting haploinsufficiency or dominant negative effect. A stop-gain mouse model was created for the heterozygous variant by PMID: 39827467 (2025), which replicated POI phenotype in women (i.e., decreased reproductive lifespan and early oocyte loss).

ii) PMID: 36030004 - two variants, p.R4del and (p.G954A in two sporadic Han Chinese POI patients. Western blot analysis further demonstrated that both of the two variants exhibited reduced mRNA and protein expression levels compared with the wild-type in vitro

iii) PMID: 38604507 - novel missense variant (p.R208H) in a patient with POI and in vitro transfection study showed that overexpression R208H significantly (P < 0.0001) lowered the overall translation efficiency, whereas exhibiting a reduced translation inhibitory effect on high-TE genes (TE > 2 in GFP control group).
