Genes affected
ASB1 (HGNC:16011): (ankyrin repeat and SOCS box containing 1) The protein encoded by this gene contains an ankyrin repeat sequence and 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, targeting them for ubiquitination and degradation.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.809C>T (p.S270L) alteration is located in exon 4 (coding exon 4) of the ASB1 gene. This alteration results from a C to T substitution at nucleotide position 809, causing the serine (S) at amino acid position 270 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
