The c.1561A>C (p.K521Q) alteration is located in exon 13 (coding exon 12) of the FAM169A gene. This alteration results from a A to C substitution at nucleotide position 1561, causing the lysine (K) at amino acid position 521 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
