Genes affected

LUC7L (HGNC:6723): (LUC7 like) The LUC7L gene may represent a mammalian heterochromatic gene, encoding a putative RNA-binding protein similar to the yeast Luc7p subunit of the U1 snRNP splicing complex that is normally required for 5-prime splice site selection (Tufarelli et al., 2001 [PubMed 11170747]).[supplied by OMIM, Mar 2008]

The c.1022G>A (p.R341Q) alteration is located in exon 10 (coding exon 10) of the LUC7L gene. This alteration results from a G to A substitution at nucleotide position 1022, causing the arginine (R) at amino acid position 341 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
