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]

Ambry Genetics

Sep 27, 2022

The c.658C>T (p.R220C) alteration is located in exon 6 (coding exon 4) of the BOC gene. This alteration results from a C to T substitution at nucleotide position 658, causing the arginine (R) at amino acid position 220 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
