Genes affected

CECR2 (HGNC:1840): (CECR2 histone acetyl-lysine reader) This gene encodes a bromodomain-containing protein that is involved in chromatin remodeling, and may additionally play a role in DNA damage response. The encoded protein functions as part of an ATP-dependent complex that is involved in neurulation. This gene is a candidate gene for Cat Eye Syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2014]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0017008781).
• BP6: Variant 22-17511843-T-G is Benign according to our data. Variant chr22-17511843-T-G is described in ClinVar as [Benign]. Clinvar id is 777644.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0684 is higher than 0.05.
