The c.100A>G (p.M34V) alteration is located in exon 3 (coding exon 2) of the PBLD gene. This alteration results from a A to G substitution at nucleotide position 100, causing the methionine (M) at amino acid position 34 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
