Description

The c.1940G>A (p.R647Q) alteration is located in exon 30 (coding exon 30) of the COL6A1 gene. This alteration results from a G to A substitution at nucleotide position 1940, causing the arginine (R) at amino acid position 647 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
