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]

Collection Method: clinical testing

The c.40C>G (p.P14A) alteration is located in exon 1 (coding exon 1) of the EMX1 gene. This alteration results from a C to G substitution at nucleotide position 40, causing the proline (P) at amino acid position 14 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
