The c.804G>C (p.Q268H) alteration is located in exon 6 (coding exon 6) of the CCDC42 gene. This alteration results from a G to C substitution at nucleotide position 804, causing the glutamine (Q) at amino acid position 268 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
