Genes affected

EMX1 (HGNC:3340): (empty spiracles homeobox 1) Enables sequence-specific double-stranded DNA binding activity. Predicted to be involved in brain development; neuron differentiation; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including nervous system development; neuroepithelial cell differentiation; and regulation of oligodendrocyte progenitor proliferation. Located in chromosome and nucleolus. [provided by Alliance of Genome Resources, Apr 2022]

The c.494A>C (p.N165T) alteration is located in exon 1 (coding exon 1) of the EMX1 gene. This alteration results from a A to C substitution at nucleotide position 494, causing the asparagine (N) at amino acid position 165 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
