The c.1291A>C (p.K431Q) alteration is located in exon 10 (coding exon 10) of the COLGALT2 gene. This alteration results from a A to C substitution at nucleotide position 1291, causing the lysine (K) at amino acid position 431 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
