The c.964A>G (p.K322E) alteration is located in exon 8 (coding exon 7) of the GALNTL6 gene. This alteration results from a A to G substitution at nucleotide position 964, causing the lysine (K) at amino acid position 322 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
