The c.641A>T (p.D214V) alteration is located in exon 3 (coding exon 3) of the CPPED1 gene. This alteration results from a A to T substitution at nucleotide position 641, causing the aspartic acid (D) at amino acid position 214 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
