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]

The c.2375C>T (p.T792M) alteration is located in exon 18 (coding exon 14) of the SEMA4D gene. This alteration results from a C to T substitution at nucleotide position 2375, causing the threonine (T) at amino acid position 792 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
