The c.464A>T (p.D155V) alteration is located in exon 3 (coding exon 3) of the MYCBPAP gene. This alteration results from a A to T substitution at nucleotide position 464, causing the aspartic acid (D) at amino acid position 155 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
