The c.1520G>A (p.R507Q) alteration is located in exon 12 (coding exon 11) of the GALNTL6 gene. This alteration results from a G to A substitution at nucleotide position 1520, causing the arginine (R) at amino acid position 507 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
