The c.440A>T (p.D147V) alteration is located in exon 7 (coding exon 6) of the USP6 gene. This alteration results from a A to T substitution at nucleotide position 440, causing the aspartic acid (D) at amino acid position 147 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
