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]

Ambry Genetics

Nov 09, 2023

The c.604A>G (p.S202G) alteration is located in exon 7 (coding exon 7) of the ABTB1 gene. This alteration results from a A to G substitution at nucleotide position 604, causing the serine (S) at amino acid position 202 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
