The c.11723T>C (p.V3908A) alteration is located in exon 70 (coding exon 69) of the HECTD4 gene. This alteration results from a T to C substitution at nucleotide position 11723, causing the valine (V) at amino acid position 3908 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
