Genes affected

LUC7L2 (HGNC:21608): (LUC7 like 2, pre-mRNA splicing factor) This gene encodes a protein that contains a C2H2-type zinc finger, coiled-coil region and arginine, serine-rich (RS) domain. A similar protein in mouse interacts with sodium channel modifier 1, and the encoded protein may be involved in the recognition of non-consensus splice donor sites in association with the U1 snRNP spliceosomal subunit. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Sep 2011]

The c.737G>A (p.R246Q) alteration is located in exon 7 (coding exon 7) of the LUC7L2 gene. This alteration results from a G to A substitution at nucleotide position 737, causing the arginine (R) at amino acid position 246 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
