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 GeneticsDec 19, 2022The c.257G>A (p.R86H) alteration is located in exon 4 (coding exon 4) of the ABTB1 gene. This alteration results from a G to A substitution at nucleotide position 257, causing the arginine (R) at amino acid position 86 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
