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: G2P, Labcorp Genetics (formerly Invitae), Ambry Genetics

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BS1: Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000195 (284/1459750) while in subpopulation NFE AF = 0.00025 (278/1110076). AF 95% confidence interval is 0.000226. There are 0 homozygotes in GnomAdExome4. There are 141 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.
