The c.1012A>C (p.I338L) alteration is located in exon 9 (coding exon 8) of the LEKR1 gene. This alteration results from a A to C substitution at nucleotide position 1012, causing the isoleucine (I) at amino acid position 338 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
