The c.931C>G (p.Q311E) alteration is located in exon 9 (coding exon 9) of the DNAJC11 gene. This alteration results from a C to G substitution at nucleotide position 931, causing the glutamine (Q) at amino acid position 311 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
