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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 1 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.0017 (below the threshold of 3.09). Trascript score misZ: 0.15829 (below the threshold of 3.09).
BP4
Computational evidence support a benign effect (MetaRNN=0.20221409).
BS2
High AC in GnomAd4 at 5 AD gene.

The c.43G>A (p.D15N) alteration is located in exon 1 (coding exon 1) of the LSM1 gene. This alteration results from a G to A substitution at nucleotide position 43, causing the aspartic acid (D) at amino acid position 15 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
