• Consequence: FEZF2 NM_018008.4 frameshift
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 5.74

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]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
