Genes affected

FOXL1 (HGNC:3817): (forkhead box L1) This gene encodes a member of the forkhead/winged helix-box (FOX) family of transcription factors. FOX transcription factors are characterized by a distinct DNA-binding forkhead domain and play critical roles in the regulation of multiple processes including metabolism, cell proliferation and gene expression during ontogenesis.

The c.379C>T (p.P127S) alteration is located in exon 1 (coding exon 1) of the FOXL1 gene. This alteration results from a C to T substitution at nucleotide position 379, causing the proline (P) at amino acid position 127 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
