Genes affected

PLXND1 (HGNC:9107): (plexin D1) Enables protein domain specific binding activity. Predicted to be involved in several processes, including endothelial cell migration; nervous system development; and regulation of angiogenesis. Predicted to act upstream of or within several processes, including circulatory system development; dichotomous subdivision of terminal units involved in salivary gland branching; and positive regulation of protein binding activity. Located in lamellipodium. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

May 23, 2023

The c.5548G>A (p.E1850K) alteration is located in exon 34 (coding exon 34) of the PLXND1 gene. This alteration results from a G to A substitution at nucleotide position 5548, causing the glutamic acid (E) at amino acid position 1850 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
