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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.659G>A (p.R220H) alteration is located in exon 6 (coding exon 4) of the BOC gene. This alteration results from a G to A substitution at nucleotide position 659, causing the arginine (R) at amino acid position 220 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
