Genes affected

FIGNL1 (HGNC:13286): (fidgetin like 1) This gene encodes a member of the AAA ATPase family of proteins. The encoded protein is recruited to sites of DNA damage where it plays a role in DNA double-strand break repair via homologous recombination. This protein has also been shown to localize to the centrosome and inhibit ciliogenesis, and may regulate the proliferation and differentiation of osteoblasts. [provided by RefSeq, Oct 2016]

The c.1448G>A (p.R483H) alteration is located in exon 4 (coding exon 1) of the FIGNL1 gene. This alteration results from a G to A substitution at nucleotide position 1448, causing the arginine (R) at amino acid position 483 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
