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 GeneticsFeb 12, 2024The c.949G>A (p.A317T) alteration is located in exon 4 (coding exon 4) of the ASB18 gene. This alteration results from a G to A substitution at nucleotide position 949, causing the alanine (A) at amino acid position 317 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
