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 Likely_benign. Variant got -6 ACMG points.

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=0.15936673).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000199 (3/150552) while in subpopulation AMR AF= 0.000131 (2/15218). AF 95% confidence interval is 0.0000227. There are 0 homozygotes in gnomad4. There are 2 alleles in male gnomad4 subpopulation. Median coverage is 31. 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 7 AD gene.

The c.47C>T (p.P16L) alteration is located in exon 1 (coding exon 1) of the NBEA gene. This alteration results from a C to T substitution at nucleotide position 47, causing the proline (P) at amino acid position 16 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
