The c.463A>G (p.M155V) alteration is located in exon 4 (coding exon 4) of the TLCD1 gene. This alteration results from a A to G substitution at nucleotide position 463, causing the methionine (M) at amino acid position 155 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
