Genes affected
ABTB1 (HGNC:18275): (ankyrin repeat and BTB domain containing 1) This gene encodes a protein with an ankyrin repeat region and two BTB/POZ domains, which are thought to be involved in protein-protein interactions. Expression of this gene is activated by the phosphatase and tensin homolog, a tumor suppressor. Alternate splicing results in three transcript variants. [provided by RefSeq, Mar 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 23, 2023The c.469A>G (p.R157G) alteration is located in exon 5 (coding exon 5) of the ABTB1 gene. This alteration results from a A to G substitution at nucleotide position 469, causing the arginine (R) at amino acid position 157 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
