Genes affected
BSG (HGNC:1116): (basigin (Ok blood group)) The protein encoded by this gene, basigin, is a plasma membrane protein that is important in spermatogenesis, embryo implantation, neural network formation, and tumor progression. Basigin is also a member of the immunoglobulin superfamily, ubiquitously expressed in various tissues. Multiple transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2023The c.596C>T (p.T199M) alteration is located in exon 5 (coding exon 5) of the BSG gene. This alteration results from a C to T substitution at nucleotide position 596, causing the threonine (T) at amino acid position 199 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
