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.1826C>T (p.T609I) alteration is located in exon 4 (coding exon 1) of the FIGNL1 gene. This alteration results from a C to T substitution at nucleotide position 1826, causing the threonine (T) at amino acid position 609 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
