Genes affected

DAB1 (HGNC:2661): (DAB adaptor protein 1) The laminar organization of multiple neuronal types in the cerebral cortex is required for normal cognitive function. In mice, the disabled-1 gene plays a central role in brain development, directing the migration of cortical neurons past previously formed neurons to reach their proper layer. This gene is similar to disabled-1, and the protein encoded by this gene is thought to be a signal transducer that interacts with protein kinase pathways to regulate neuronal positioning in the developing brain.

Ambry Genetics

Nov 15, 2021

The c.1660G>A (p.G554S) alteration is located in exon 16 (coding exon 13) of the DAB1 gene. This alteration results from a G to A substitution at nucleotide position 1660, causing the glycine (G) at amino acid position 554 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
