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]

ELP2 Gene-Disease associations (from GenCC):

• intellectual disability, autosomal recessive 58

  Inheritance: AR Classification: STRONG, MODERATE, LIMITED Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004386574).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.369 is higher than 0.05.
