Genes affected

BANK1 (HGNC:18233): (B cell scaffold protein with ankyrin repeats 1) The protein encoded by this gene is a B-cell-specific scaffold protein that functions in B-cell receptor-induced calcium mobilization from intracellular stores. This protein can also promote Lyn-mediated tyrosine phosphorylation of inositol 1,4,5-trisphosphate receptors. Polymorphisms in this gene are associated with susceptibility to systemic lupus erythematosus. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

BANK1 Gene-Disease associations (from GenCC):

• systemic lupus erythematosus

  Inheritance: Unknown Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.64).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.124 is higher than 0.05.
