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.1142G>A (p.R381Q) alteration is located in exon 9 (coding exon 9) of the LSM14A gene. This alteration results from a G to A substitution at nucleotide position 1142, causing the arginine (R) at amino acid position 381 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
