Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.5C>A (p.A2E) alteration is located in exon 1 (coding exon 1) of the PLXDC2 gene. This alteration results from a C to A substitution at nucleotide position 5, causing the alanine (A) at amino acid position 2 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
