The c.1085T>A (p.M362K) alteration is located in exon 11 (coding exon 9) of the CLGN gene. This alteration results from a T to A substitution at nucleotide position 1085, causing the methionine (M) at amino acid position 362 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
