Genes affected
NBEA (HGNC:7648): (neurobeachin) This gene encodes a member of a large, diverse group of A-kinase anchor proteins that target the activity of protein kinase A to specific subcellular sites by binding to its type II regulatory subunits. Brain-specific expression and coat protein-like membrane recruitment of a highly similar protein in mouse suggest an involvement in neuronal post-Golgi membrane traffic. Mutations in this gene may be associated with a form of autism. This gene and its expression are frequently disrupted in patients with multiple myeloma. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional transcript variants may exist, but their full-length nature has not been determined.[provided by RefSeq, Feb 2011]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.83).
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000124 (15/1208472) while in subpopulation SAS AF= 0.000198 (11/55534). AF 95% confidence interval is 0.000111. There are 0 homozygotes in gnomad4_exome. There are 9 alleles in male gnomad4_exome subpopulation. Median coverage is 27. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAdExome4 at 15 AD gene.

Uncertain significance, criteria provided, single submitterclinical testingWomen's Health and Genetics/Laboratory Corporation of America, LabCorpJul 02, 2024Variant summary: NBEA c.-8G>T is located in the untranslated mRNA region upstream of the initiation codon. The variant was absent in 11774 control chromosomes. The available data on variant occurrences in the general population are insufficient to allow any conclusion about variant significance. To our knowledge, no occurrence of c.-8G>T in individuals affected with Neurodevelopmental Disorder With Or Without Early-Onset Generalized Epilepsy and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar. Based on the evidence outlined above, the variant was classified as uncertain significance. -
