Genes affected
RNF139 (HGNC:17023): (ring finger protein 139) The protein encoded by this gene is a multi-membrane spanning protein containing a RING-H2 finger. This protein is located in the endoplasmic reticulum, and has been shown to possess ubiquitin ligase activity. This gene was found to be interrupted by a t(3:8) translocation in a family with hereditary renal and non-medulary thyroid cancer. Studies of the Drosophila counterpart suggested that this protein may interact with tumor suppressor protein VHL, as well as with COPS5/JAB1, a protein responsible for the degradation of tumor suppressor CDKN1B/P27KIP.

The c.125C>T (p.P42L) alteration is located in exon 1 (coding exon 1) of the RNF139 gene. This alteration results from a C to T substitution at nucleotide position 125, causing the proline (P) at amino acid position 42 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
