The c.1021A>G (p.M341V) alteration is located in exon 8 (coding exon 8) of the TIMD4 gene. This alteration results from a A to G substitution at nucleotide position 1021, causing the methionine (M) at amino acid position 341 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
