Genes affected

ELP2 (HGNC:18248): (elongator acetyltransferase complex subunit 2) The protein encoded by this gene is a core subunit of the elongator complex, a histone acetyltransferase complex that associates with RNA polymerase II. In addition to histone acetylation, the encoded protein effects transcriptional elongation and may help remodel chromatin. [provided by RefSeq, May 2016]

The c.56G>A (p.R19Q) alteration is located in exon 1 (coding exon 1) of the ELP2 gene. This alteration results from a G to A substitution at nucleotide position 56, causing the arginine (R) at amino acid position 19 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
