Genes affected

EML4 (HGNC:1316): (EMAP like 4) This gene is a member of the echinoderm microtubule associated protein-like family. The encoded WD-repeat protein may be involved in microtubule formation. Abnormal fusion of parts of this gene with portions of the anaplastic lymphoma receptor tyrosine kinase gene, which generates EML4-ALK fusion transcripts, is one of the primary mutations associated with non-small cell lung cancer. Alternative splicing of this gene results in two transcript variants. [provided by RefSeq, Jan 2015]

The c.574C>T (p.R192C) alteration is located in exon 5 (coding exon 5) of the EML4 gene. This alteration results from a C to T substitution at nucleotide position 574, causing the arginine (R) at amino acid position 192 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
