Genes affected
SEMA3D (HGNC:10726): (semaphorin 3D) This gene encodes a member of the semaphorin III family of secreted signaling proteins that are involved in axon guidance during neuronal development. The encoded protein contains an N-terminal Sema domain, an immunoglobulin like domain and a C-terminal basic domain. The protein encoded by this gene binds neuropilin and plays an important role in cardiovascular development. [provided by RefSeq, Aug 2016]

SEMA3D-related disorder Uncertain:1
Uncertain significance, no assertion criteria providedclinical testingPreventionGenetics, part of Exact SciencesJul 29, 2024The SEMA3D c.2114T>G variant is predicted to result in the amino acid substitution p.Leu705Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0062% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
