The c.827G>A (p.G276E) alteration is located in exon 10 (coding exon 9) of the PBLD gene. This alteration results from a G to A substitution at nucleotide position 827, causing the glycine (G) at amino acid position 276 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
