Genes affected
ZBTB21 (HGNC:13083): (zinc finger and BTB domain containing 21) Enables several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; POZ domain binding activity; and methyl-CpG binding activity. Involved in negative regulation of transcription by RNA polymerase II. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 27, 2021The c.2368A>G (p.I790V) alteration is located in exon 3 (coding exon 1) of the ZBTB21 gene. This alteration results from a A to G substitution at nucleotide position 2368, causing the isoleucine (I) at amino acid position 790 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
