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]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a modified_residue N-acetylalanine (size 0) in uniprot entity IGBP1_HUMAN
• PM2: Very rare variant in population databases, with high coverage

The IGBP1 c.5C>G (p.Ala2Gly) variant is a missense variant. A literature search was performed for the gene, cDNA change, and amino acid change. No publications were found based on this search. This variant is not found in the Genome Aggregation Database despite its location in a region of good sequencing coverage, which suggests the variant is rare. Based on the available information, the p.Ala2Gly variant is classified as a variant of uncertain significance. -
