Genes affected

MVP (HGNC:7531): (major vault protein) This gene encodes the major component of the vault complex. Vaults are multi-subunit ribonucleoprotein structures that may be involved in nucleo-cytoplasmic transport. The encoded protein may play a role in multiple cellular processes by regulating the MAP kinase, JAK/STAT and phosphoinositide 3-kinase/Akt signaling pathways. The encoded protein also plays a role in multidrug resistance, and expression of this gene may be a prognostic marker for several types of cancer. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, May 2012]

The c.454A>C (p.I152L) alteration is located in exon 5 (coding exon 4) of the MVP gene. This alteration results from a A to C substitution at nucleotide position 454, causing the isoleucine (I) at amino acid position 152 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
