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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2024The c.259G>A (p.A87T) alteration is located in exon 2 (coding exon 2) of the SEMA4F gene. This alteration results from a G to A substitution at nucleotide position 259, causing the alanine (A) at amino acid position 87 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
