The c.4409T>C (p.V1470A) alteration is located in exon 23 (coding exon 23) of the FAM208A gene. This alteration results from a T to C substitution at nucleotide position 4409, causing the valine (V) at amino acid position 1470 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
