The c.1372A>T (p.M458L) alteration is located in exon 4 (coding exon 4) of the EMILIN3 gene. This alteration results from a A to T substitution at nucleotide position 1372, causing the methionine (M) at amino acid position 458 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
