Genes affected

FIGLA (HGNC:24669): (folliculogenesis specific bHLH transcription factor) This gene encodes a protein that functions in postnatal oocyte-specific gene expression. The protein is a basic helix-loop-helix transcription factor that regulates multiple oocyte-specific genes, including genes involved in folliculogenesis and those that encode the zona pellucida. Mutations in this gene cause premature ovarian failure type 6. [provided by RefSeq, Sep 2009]

The c.491T>G (p.F164C) alteration is located in exon 3 (coding exon 3) of the FIGLA gene. This alteration results from a T to G substitution at nucleotide position 491, causing the phenylalanine (F) at amino acid position 164 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
