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. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 08, 2022The c.354C>G (p.C118W) alteration is located in exon 3 (coding exon 2) of the IGBP1 gene. This alteration results from a C to G substitution at nucleotide position 354, causing the cysteine (C) at amino acid position 118 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
