The c.20236G>C (p.D6746H) alteration is located in exon 4 (coding exon 4) of the CCDC168 gene. This alteration results from a G to C substitution at nucleotide position 20236, causing the aspartic acid (D) at amino acid position 6746 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
