The c.282C>G (p.D94E) alteration is located in exon 2 (coding exon 2) of the PLXDC2 gene. This alteration results from a C to G substitution at nucleotide position 282, causing the aspartic acid (D) at amino acid position 94 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
