The c.67G>T (p.A23S) alteration is located in exon 1 (coding exon 1) of the LMOD2 gene. This alteration results from a G to T substitution at nucleotide position 67, causing the alanine (A) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
