The c.1063C>G (p.H355D) alteration is located in exon 10 (coding exon 10) of the HECTD2 gene. This alteration results from a C to G substitution at nucleotide position 1063, causing the histidine (H) at amino acid position 355 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
