Genes affected

IGBP1 (HGNC:5461): (immunoglobulin binding protein 1) The proliferation and differentiation of B cells is dependent upon a B-cell antigen receptor (BCR) complex. Binding of antigens to specific B-cell receptors results in a tyrosine phosphorylation reaction through the BCR complex and leads to multiple signal transduction pathways.

The c.410A>T (p.H137L) alteration is located in exon 3 (coding exon 2) of the IGBP1 gene. This alteration results from a A to T substitution at nucleotide position 410, causing the histidine (H) at amino acid position 137 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
