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

Classification made for transcript

Verdict is Likely_benign. Variant got -5 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), ZBTB18. . Gene score misZ 3.4305 (greater than the threshold 3.09). Trascript score misZ 4.2468 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 22, complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.12054312).
BS2
High AC in GnomAdExome4 at 39 AD gene.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 27, 2022The c.10A>G (p.K4E) alteration is located in exon 1 (coding exon 1) of the ZBTB18 gene. This alteration results from a A to G substitution at nucleotide position 10, causing the lysine (K) at amino acid position 4 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
