Genes affected

LSM14A (HGNC:24489): (LSM14A mRNA processing body assembly factor) Sm-like proteins were identified in a variety of organisms based on sequence homology with the Sm protein family (see SNRPD2; 601061). Sm-like proteins contain the Sm sequence motif, which consists of 2 regions separated by a linker of variable length that folds as a loop. The Sm-like proteins are thought to form a stable heteromer present in tri-snRNP particles, which are important for pre-mRNA splicing.[supplied by OMIM, Mar 2008]

The c.421A>G (p.S141G) alteration is located in exon 4 (coding exon 4) of the LSM14A gene. This alteration results from a A to G substitution at nucleotide position 421, causing the serine (S) at amino acid position 141 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
