Dec 21, 2022

The c.899C>A (p.T300K) alteration is located in exon 8 (coding exon 8) of the PLXDC2 gene. This alteration results from a C to A substitution at nucleotide position 899, causing the threonine (T) at amino acid position 300 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
