Genes affected

ASB5 (HGNC:17180): (ankyrin repeat and SOCS box containing 5) 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 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. Multiple alternatively spliced transcript variants have been described for this gene but their full length sequences are not known. [provided by RefSeq, Jul 2008]

The c.269T>C (p.L90S) alteration is located in exon 2 (coding exon 2) of the ASB5 gene. This alteration results from a T to C substitution at nucleotide position 269, causing the leucine (L) at amino acid position 90 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
