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]

The c.5323A>G (p.I1775V) alteration is located in exon 33 (coding exon 33) of the PLXND1 gene. This alteration results from a A to G substitution at nucleotide position 5323, causing the isoleucine (I) at amino acid position 1775 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
