Collection Method: clinical testing

The c.2307T>G (p.C769W) alteration is located in exon 6 (coding exon 5) of the FAM214A gene. This alteration results from a T to G substitution at nucleotide position 2307, causing the cysteine (C) at amino acid position 769 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
