Genes affected
SNRPB (HGNC:11153): (small nuclear ribonucleoprotein polypeptides B and B1) The protein encoded by this gene is one of several nuclear proteins that are found in common among U1, U2, U4/U6, and U5 small ribonucleoprotein particles (snRNPs). These snRNPs are involved in pre-mRNA splicing, and the encoded protein may also play a role in pre-mRNA splicing or snRNP structure. Autoantibodies from patients with systemic lupus erythematosus frequently recognize epitopes on the encoded protein. Two transcript variants encoding different isoforms (B and B') have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.25).
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000547 (20/365334) while in subpopulation AMR AF= 0.000448 (13/28994). AF 95% confidence interval is 0.000265. There are 0 homozygotes in gnomad4_exome. There are 9 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck.
