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]

Ambry Genetics

May 02, 2024

The c.4200T>A (p.F1400L) alteration is located in exon 38 (coding exon 37) of the HFM1 gene. This alteration results from a T to A substitution at nucleotide position 4200, causing the phenylalanine (F) at amino acid position 1400 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
