The c.12235C>T (p.R4079W) alteration is located in exon 73 (coding exon 72) of the HECTD4 gene. This alteration results from a C to T substitution at nucleotide position 12235, causing the arginine (R) at amino acid position 4079 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
