Genetic Variant SEMA4D:p.Arg357Pro (chr9-89388673-C-G) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_001371194.2(SEMA4D):c.1070G>C(p.Arg357Pro) variant causes a missense change. The variant allele was found at a frequency of 0.0000081 in 1,604,198 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R357H) has been classified as Uncertain significance.

Genes affected

SEMA4D (HGNC:10732): (semaphorin 4D) Enables identical protein binding activity; semaphorin receptor binding activity; and transmembrane signaling receptor activity. Involved in several processes, including positive regulation of phosphatidylinositol 3-kinase signaling; regulation of neuron projection development; and regulation of phosphate metabolic process. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
