The c.1292C>T (p.S431L) alteration is located in exon 12 (coding exon 10) of the CLGN gene. This alteration results from a C to T substitution at nucleotide position 1292, causing the serine (S) at amino acid position 431 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
