Collection Method: clinical testing

The c.650A>T (p.D217V) alteration is located in exon 5 (coding exon 5) of the EFCAB14 gene. This alteration results from a A to T substitution at nucleotide position 650, causing the aspartic acid (D) at amino acid position 217 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
