Genes affected

ASB2 (HGNC:16012): (ankyrin repeat and SOCS box containing 2) This gene encodes a member of the ankyrin repeat and SOCS box-containing (ASB) protein family. These proteins play a role in protein degradation by coupling suppressor of cytokine signalling (SOCS) proteins with the elongin BC complex. The encoded protein is a subunit of a multimeric E3 ubiquitin ligase complex that mediates the degradation of actin-binding proteins. This gene plays a role in retinoic acid-induced growth inhibition and differentiation of myeloid leukemia cells. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jan 2011]

The c.1572G>T (p.R524S) alteration is located in exon 8 (coding exon 7) of the ASB2 gene. This alteration results from a G to T substitution at nucleotide position 1572, causing the arginine (R) at amino acid position 524 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
