The c.1456T>G (p.L486V) alteration is located in exon 13 (coding exon 11) of the CLGN gene. This alteration results from a T to G substitution at nucleotide position 1456, causing the leucine (L) at amino acid position 486 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
