Genes affected

SEMA5A (HGNC:10736): (semaphorin 5A) This gene belongs to the semaphorin gene family that encodes membrane proteins containing a semaphorin domain and several thrombospondin type-1 repeats. Members of this family are involved in axonal guidance during neural development. This gene has been implicated as an autism susceptibility gene.[provided by RefSeq, Jan 2010]

The c.2813G>A (p.R938Q) alteration is located in exon 20 (coding exon 18) of the SEMA5A gene. This alteration results from a G to A substitution at nucleotide position 2813, causing the arginine (R) at amino acid position 938 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
