Genes affected
HFM1 (HGNC:20193): (helicase for meiosis 1) The protein encoded by this gene is thought to be an ATP-dependent DNA helicase and is expressed mainly in germ-line cells. Defects in this gene are a cause of premature ovarian failure 9 (POF9). [provided by RefSeq, Apr 2014]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.3687A>G (p.I1229M) alteration is located in exon 34 (coding exon 33) of the HFM1 gene. This alteration results from a A to G substitution at nucleotide position 3687, causing the isoleucine (I) at amino acid position 1229 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
