Genes affected

ASB18 (HGNC:19770): (ankyrin repeat and SOCS box containing 18) The protein encoded by this gene is a member of the ankyrin repeat and SOCS box-containing (ASB) family of proteins. They contain ankyrin repeat sequence and a SOCS box domain. The SOCS box serves to couple suppressor of cytokine signalling (SOCS) proteins and their binding partners with the elongin B and C complex, possibly targeting them for degradation.

Jul 20, 2021

The c.1300A>G (p.R434G) alteration is located in exon 6 (coding exon 6) of the ASB18 gene. This alteration results from a A to G substitution at nucleotide position 1300, causing the arginine (R) at amino acid position 434 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
