The c.946G>C (p.E316Q) alteration is located in exon 2 (coding exon 1) of the C2CD4C gene. This alteration results from a G to C substitution at nucleotide position 946, causing the glutamic acid (E) at amino acid position 316 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
