Ambry Genetics

Sep 26, 2023

The c.264C>G (p.C88W) alteration is located in exon 4 (coding exon 2) of the FAM24B gene. This alteration results from a C to G substitution at nucleotide position 264, causing the cysteine (C) at amino acid position 88 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
