Genes affected

SEMA4F (HGNC:10734): (ssemaphorin 4F) This gene encodes a transmembrane class IV semaphorin family protein, which plays a role in neural development. This gene may be involved in neurogenesis in prostate cancer, the development of neurofibromas, and breast cancer tumorigenesis. Alternative splicing results in multiple transcript variants.

Ambry Genetics

Oct 04, 2022

The c.500G>A (p.R167Q) alteration is located in exon 5 (coding exon 5) of the SEMA4F gene. This alteration results from a G to A substitution at nucleotide position 500, causing the arginine (R) at amino acid position 167 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
