Genes affected
BST2 (HGNC:1119): (bone marrow stromal cell antigen 2) Bone marrow stromal cells are involved in the growth and development of B-cells. The specific function of the protein encoded by the bone marrow stromal cell antigen 2 is undetermined; however, this protein may play a role in pre-B-cell growth and in rheumatoid arthritis.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 07, 2024The c.440G>C (p.R147T) alteration is located in exon 4 (coding exon 4) of the BST2 gene. This alteration results from a G to C substitution at nucleotide position 440, causing the arginine (R) at amino acid position 147 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
