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]

FMC1-LUC7L2 (HGNC:44671): (FMC1-LUC7L2 readthrough) This locus represents naturally occurring readthrough transcription between the neighboring C7orf55 (chromosome 7 open reading frame 55) and LUC7L2 (LUC7-like 2) genes on chromosome 7. The readthrough transcript encodes a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Jul 2012]

ENSG00000310166 (HGNC:):

ACMG classification
