Genes affected

BCAM (HGNC:6722): (basal cell adhesion molecule (Lutheran blood group)) This gene encodes Lutheran blood group glycoprotein, a member of the immunoglobulin superfamily and a receptor for the extracellular matrix protein, laminin. The protein contains five extracellular immunoglobulin domains, a single transmembrane domain, and a short C-terminal cytoplasmic tail. This protein may play a role in epithelial cell cancer and in vaso-occlusion of red blood cells in sickle cell disease. Polymorphisms in this gene define some of the antigens in the Lutheran system and also the Auberger system. Inactivating variants of this gene result in the recessive Lutheran null phenotype, Lu(a-b-), of the Lutheran blood group. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2012]

Ambry Genetics

Nov 29, 2023

The c.370G>A (p.V124M) alteration is located in exon 3 (coding exon 3) of the BCAM gene. This alteration results from a G to A substitution at nucleotide position 370, causing the valine (V) at amino acid position 124 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
