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 Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NBEA. . Gene score misZ 5.5108 (greater than the threshold 3.09). Trascript score misZ 5.4439 (greater than threshold 3.09). GenCC has associacion of gene with syndromic intellectual disability, neurodevelopmental disorder with or without early-onset generalized epilepsy, complex neurodevelopmental disorder.

BP4

Computational evidence support a benign effect (MetaRNN=0.07224539).

The c.119G>C (p.S40T) alteration is located in exon 1 (coding exon 1) of the NBEA gene. This alteration results from a G to C substitution at nucleotide position 119, causing the serine (S) at amino acid position 40 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
