Genes affected

ZBTB18 (HGNC:13030): (zinc finger and BTB domain containing 18) This gene encodes a C2H2-type zinc finger protein which acts a transcriptional repressor of genes involved in neuronal development. The encoded protein recognizes a specific sequence motif and recruits components of chromatin to target genes. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 45 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-244054372-TC-T is Pathogenic according to our data. Variant chr1-244054372-TC-T is described in ClinVar as [Pathogenic]. Clinvar id is 397517.Status of the report is criteria_provided_single_submitter, 1 stars.
