Genes affected

BOC (HGNC:17173): (BOC cell adhesion associated, oncogene regulated) The protein encoded by this gene is a member of the immunoglobulin/fibronectin type III repeat family. It is a component of a cell-surface receptor complex that mediates cell-cell interactions between muscle precursor cells, and promotes myogenic differentiation. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Sep 2014]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.22112012).

The c.947A>G (p.N316S) alteration is located in exon 7 (coding exon 5) of the BOC gene. This alteration results from a A to G substitution at nucleotide position 947, causing the asparagine (N) at amino acid position 316 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
