Genetic Variant SEMA4D:p.Ala72Ser (chr9-89402909-C-A) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_001371194.2(SEMA4D):c.214G>T(p.Ala72Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000496 in 1,613,934 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. 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. A72T) has been classified as Benign.

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]
