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.

GBX2-AS1 (HGNC:55714): (GBX2 and ASB18 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.1100A>G (p.K367R) alteration is located in exon 4 (coding exon 4) of the ASB18 gene. This alteration results from a A to G substitution at nucleotide position 1100, causing the lysine (K) at amino acid position 367 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
