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]

HFM1 Gene-Disease associations (from GenCC):

• premature ovarian failure 9

  Inheritance: Unknown Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)
• male infertility with azoospermia or oligozoospermia due to single gene mutation

  Inheritance: AR Classification: NO_KNOWN Submitted by: King Faisal Specialist Hospital and Research Center

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.259 is higher than 0.05.
