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]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Likely Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with neurodevelopmental disorder (MONDO:0700092), FEZF2-related. (I) 0107 - This gene is associated with autosomal dominant disease (PMID: 38425142). (I) 0200 - Variant is predicted to result in a missense amino acid change from cysteine to tryptophan. (I) 0251 - This variant is heterozygous. (I) 0301 - Variant is absent from gnomAD (both v2 and v3). (SP) 0501 - Missense variant consistently predicted to be damaging by multiple in silico tools or highly conserved with a major amino acid change. (SP) 0603 - Missense variant in a region that is highly intolerant to missense variation (high constraint region in DECIPHER). (SP) 0705 - No comparable missense variants have previous evidence for pathogenicity. (I) 0807 - This variant has no previous evidence of pathogenicity. (I) 0905 - No published segregation evidence has been identified for this variant. (I) 1007 - No published functional evidence has been identified for this variant. (I) 1203 - This variant has been shown to be de novo in the proband (parental status confirmed) (by trio analysis). (SP) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -
