Genes affected

CELF1 (HGNC:2549): (CUGBP Elav-like family member 1) Members of the CELF/BRUNOL protein family contain two N-terminal RNA recognition motif (RRM) domains, one C-terminal RRM domain, and a divergent segment of 160-230 aa between the second and third RRM domains. Members of this protein family regulate pre-mRNA alternative splicing and may also be involved in mRNA editing, and translation. This gene may play a role in myotonic dystrophy type 1 (DM1) via interactions with the dystrophia myotonica-protein kinase (DMPK) gene. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

The c.1160A>G (p.Q387R) alteration is located in exon 13 (coding exon 11) of the CELF1 gene. This alteration results from a A to G substitution at nucleotide position 1160, causing the glutamine (Q) at amino acid position 387 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
