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: Pathogenic. The variant received 11 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-91266061-GG-C is Pathogenic according to our data. Variant chr1-91266061-GG-C is described in ClinVar as Pathogenic. ClinVar VariationId is 126431.Status of the report is no_assertion_criteria_provided, 0 stars.
