Genes affected

ELP4 (HGNC:1171): (elongator acetyltransferase complex subunit 4) This gene encodes a component of the six subunit elongator complex, a histone acetyltransferase complex that associates directly with RNA polymerase II during transcriptional elongation. The human gene can partially complement sensitivity phenotypes of yeast ELP4 deletion mutants. This gene has also been associated with Rolandic epilepsy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

Collection Method:clinical testing

The c.245C>G (p.T82R) alteration is located in exon 2 (coding exon 2) of the ELP4 gene. This alteration results from a C to G substitution at nucleotide position 245, causing the threonine (T) at amino acid position 82 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
