Genes affected

LSM1 (HGNC:20472): (LSM1 homolog, mRNA degradation associated) This gene encodes a member of the LSm family of RNA-binding proteins. LSm proteins form stable heteromers that bind specifically to the 3'-terminal oligo(U) tract of U6 snRNA and may play a role in pre-mRNA splicing by mediating U4/U6 snRNP formation. Increased expression of this gene may play a role in cellular transformation and the progression of several malignancies including lung cancer, mesothelioma and breast cancer. Alternatively spliced transcript variants have been observed for this gene, and a pseudogene of this gene is located on the short arm of chromosome 9. [provided by RefSeq, Nov 2011]

The c.193G>A (p.V65M) alteration is located in exon 3 (coding exon 3) of the LSM1 gene. This alteration results from a G to A substitution at nucleotide position 193, causing the valine (V) at amino acid position 65 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
