Genes affected
MAP1B (HGNC:6836): (microtubule associated protein 1B) This gene encodes a protein that belongs to the microtubule-associated protein family. The proteins of this family are thought to be involved in microtubule assembly, which is an essential step in neurogenesis. The product of this gene is a precursor polypeptide that presumably undergoes proteolytic processing to generate the final MAP1B heavy chain and LC1 light chain. Gene knockout studies of the mouse microtubule-associated protein 1B gene suggested an important role in development and function of the nervous system. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 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), MAP1B. . Gene score misZ 2.5114 (greater than the threshold 3.09). Trascript score misZ 3.9037 (greater than threshold 3.09). GenCC has associacion of gene with periventricular nodular heterotopia, periventricular nodular heterotopia 9.
BP4
Computational evidence support a benign effect (MetaRNN=0.3724561).
