Genes affected
ZBTB49 (HGNC:19883): (zinc finger and BTB domain containing 49) Enables DNA-binding transcription factor binding activity; sequence-specific DNA binding activity; and transcription coactivator binding activity. Involved in negative regulation of cell population proliferation; positive regulation of transcription by RNA polymerase II; and regulation of cell cycle. Located in cytosol; microtubule cytoskeleton; 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 16, 2021The c.1187C>T (p.A396V) alteration is located in exon 3 (coding exon 2) of the ZBTB49 gene. This alteration results from a C to T substitution at nucleotide position 1187, causing the alanine (A) at amino acid position 396 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
