This sequence change is predicted to cause a change in the length of the protein due to an in-frame deletion of one amino acid in a non-repeat region of the C14orf39 protein, p.(Val411del). The region deleted is weakly conserved (100 vertebrates, UCSC), and is not located in an annotated domain. The highest population minor allele frequency in gnomAD v2.1 is 0.0008% (1/127,796 alleles) in the European (non-Finnish) population, which is consistent with recessive disease. To our knowledge, this variant has not been reported in the literature in any individuals with premature ovarian insufficiency. Based on the classification scheme RMH Modified ACMG Guidelines v1.5.1, this variant is classified as a VARIANT OF UNCERTAIN SIGNIFICANCE. Following criteria are met: PM2_Supporting, PM4_Supporting. -
