The c.745G>C (p.E249Q) alteration is located in exon 9 (coding exon 8) of the PBLD gene. This alteration results from a G to C substitution at nucleotide position 745, causing the glutamic acid (E) at amino acid position 249 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
