Genes affected
ZBTB20 (HGNC:13503): (zinc finger and BTB domain containing 20) This gene, which was initially designated as dendritic cell-derived BTB/POZ zinc finger (DPZF), belongs to a family of transcription factors with an N-terminal BTB/POZ domain and a C-terminal DNA-bindng zinc finger domain. The BTB/POZ domain is a hydrophobic region of approximately 120 aa which mediates association with other BTB/POZ domain-containing proteins. This gene acts as a transcriptional repressor and plays a role in many processes including neurogenesis, glucose homeostasis, and postnatal growth. Mutations in this gene have been associated with Primrose syndrome as well as the 3q13.31 microdeletion syndrome. Alternative splicing results in multiple transcript variants encoding distinct isoforms. [provided by RefSeq, Feb 2017]

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), ZBTB20. . Gene score misZ: 4.272 (greater than the threshold 3.09). Trascript score misZ: 3.9474 (greater than threshold 3.09). The gene has 48 curated pathogenic missense variants (we use a threshold of 10). The gene has 23 curated benign missense variants. GenCC has associacion of the gene with Primrose syndrome, diabetes mellitus.
BP4
Computational evidence support a benign effect (MetaRNN=0.12380859).
BS2
High AC in GnomAdExome4 at 51 AD gene.
