The c.1349C>T (p.A450V) alteration is located in exon 4 (coding exon 4) of the FAM161B gene. This alteration results from a C to T substitution at nucleotide position 1349, causing the alanine (A) at amino acid position 450 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
