The c.820A>G (p.I274V) alteration is located in exon 10 (coding exon 9) of the PBLD gene. This alteration results from a A to G substitution at nucleotide position 820, causing the isoleucine (I) at amino acid position 274 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
