Genes affected

NAV1 (HGNC:15989): (neuron navigator 1) This gene belongs to the neuron navigator family and is expressed predominantly in the nervous system. The encoded protein contains coiled-coil domains and a conserved AAA domain characteristic for ATPases associated with a variety of cellular activities. This gene is similar to unc-53, a Caenorhabditis elegans gene involved in axon guidance. The exact function of this gene is not known, but it is thought to play a role in in neuronal development and regeneration. Alternative splicing results in multiple transcript variants.

The c.581G>A (p.S194N) alteration is located in exon 1 (coding exon 1) of the NAV1 gene. This alteration results from a G to A substitution at nucleotide position 581, causing the serine (S) at amino acid position 194 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
