Genes affected

FEZF2 (HGNC:13506): (FEZ family zinc finger 2) Predicted to enable transcription cis-regulatory region binding activity. Predicted to be involved in positive regulation of transcription, DNA-templated. Predicted to act upstream of or within several processes, including negative regulation of transcription by RNA polymerase II; nervous system development; and regulation of neuron differentiation. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.493G>A (p.A165T) alteration is located in exon 2 (coding exon 1) of the FEZF2 gene. This alteration results from a G to A substitution at nucleotide position 493, causing the alanine (A) 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. -
