The c.770C>T (p.A257V) alteration is located in exon 4 (coding exon 3) of the FAM53B gene. This alteration results from a C to T substitution at nucleotide position 770, causing the alanine (A) at amino acid position 257 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
