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.5537C>T (p.T1846M) alteration is located in exon 34 (coding exon 34) of the PLXND1 gene. This alteration results from a C to T substitution at nucleotide position 5537, causing the threonine (T) at amino acid position 1846 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
