Genes affected

SELENBP1 (HGNC:10719): (selenium binding protein 1) This gene encodes a member of the selenium-binding protein family. Selenium is an essential nutrient that exhibits potent anticarcinogenic properties, and deficiency of selenium may cause certain neurologic diseases. The effects of selenium in preventing cancer and neurologic diseases may be mediated by selenium-binding proteins, and decreased expression of this gene may be associated with several types of cancer. The encoded protein may play a selenium-dependent role in ubiquitination/deubiquitination-mediated protein degradation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Apr 2012]

The c.1028C>T (p.P343L) alteration is located in exon 9 (coding exon 9) of the SELENBP1 gene. This alteration results from a C to T substitution at nucleotide position 1028, causing the proline (P) at amino acid position 343 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
