The c.862G>A (p.A288T) 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 862, causing the alanine (A) at amino acid position 288 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
