Genes affected

ASB16 (HGNC:19768): (ankyrin repeat and SOCS box containing 16) 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.

The c.36G>A (p.M12I) alteration is located in exon 1 (coding exon 1) of the ASB16 gene. This alteration results from a G to A substitution at nucleotide position 36, causing the methionine (M) at amino acid position 12 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
