Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 6P and 0B. PM2 PP3_Strong

The NM_018008.4(FEZF2):​c.1171T>G​(p.Cys391Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 12/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

• Frequency: Genomes: not found (cov: 33)
• Consequence: FEZF2 NM_018008.4 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 9.32

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 Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.949
