Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.1727G>T (p.C576F) alteration is located in exon 2 (coding exon 1) of the FIGNL2 gene. This alteration results from a G to T substitution at nucleotide position 1727, causing the cysteine (C) at amino acid position 576 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
