Genes affected

SLIT3 (HGNC:11087): (slit guidance ligand 3) The protein encoded by this gene is secreted, likely interacting with roundabout homolog receptors to effect cell migration. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2012]

SLIT3-AS2 (HGNC:40551): (SLIT3 antisense RNA 2)

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.48).
• BP7: Synonymous conserved (PhyloP=-0.587 with no splicing effect.
