The c.1808G>A (p.R603H) alteration is located in exon 16 (coding exon 14) of the CLGN gene. This alteration results from a G to A substitution at nucleotide position 1808, causing the arginine (R) at amino acid position 603 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
