The c.935A>T (p.K312M) alteration is located in exon 4 (coding exon 4) of the LANCL3 gene. This alteration results from a A to T substitution at nucleotide position 935, causing the lysine (K) at amino acid position 312 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
