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=0.1607134).

The c.112G>T (p.V38F) alteration is located in exon 4 (coding exon 2) of the BOC gene. This alteration results from a G to T substitution at nucleotide position 112, causing the valine (V) at amino acid position 38 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
