Genes affected

SEMA6C (HGNC:10740): (semaphorin 6C) This gene encodes a member of the semaphorin family. Semaphorins represent important molecular signals controlling multiple aspects of the cellular response that follows CNS injury, and thus may play an important role in neural regeneration.

Ambry Genetics

Aug 16, 2021

The c.2222T>C (p.V741A) alteration is located in exon 20 (coding exon 18) of the SEMA6C gene. This alteration results from a T to C substitution at nucleotide position 2222, causing the valine (V) at amino acid position 741 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
