The c.535G>T (p.V179L) alteration is located in exon 4 (coding exon 4) of the MPZL3 gene. This alteration results from a G to T substitution at nucleotide position 535, causing the valine (V) at amino acid position 179 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
