Position:

• chr6-109481260-C-A

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_014797.3(ZBTB24):​c.767G>T​(p.Arg256Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R256Q) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 32)
• Consequence: ZBTB24 NM_014797.3 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 5.50

Genes affected

ZBTB24 (HGNC:21143): (zinc finger and BTB domain containing 24) Predicted to enable DNA-binding transcription factor activity and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within hematopoietic progenitor cell differentiation. Predicted to be located in nucleus. Implicated in immunodeficiency-centromeric instability-facial anomalies syndrome 2. [provided by Alliance of Genome Resources, Apr 2022]
