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]

The c.277G>T (p.A93S) alteration is located in exon 4 (coding exon 4) of the ABTB1 gene. This alteration results from a G to T substitution at nucleotide position 277, causing the alanine (A) at amino acid position 93 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
