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.

The c.1606C>G (p.P536A) alteration is located in exon 16 (coding exon 13) of the DAB1 gene. This alteration results from a C to G substitution at nucleotide position 1606, causing the proline (P) at amino acid position 536 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
