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]

The c.3998C>T (p.S1333L) alteration is located in exon 37 (coding exon 36) of the HFM1 gene. This alteration results from a C to T substitution at nucleotide position 3998, causing the serine (S) at amino acid position 1333 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
