The c.718G>C (p.E240Q) alteration is located in exon 5 (coding exon 5) of the DNAJB14 gene. This alteration results from a G to C substitution at nucleotide position 718, causing the glutamic acid (E) at amino acid position 240 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
