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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.05).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.951 is higher than 0.05.
