Pittsburgh Clinical Genomics Laboratory, University of Pittsburgh Medical Center RCV004784922 SCV005397176 likely pathogenic Snijders Blok-Campeau syndrome 2023-02-13 criteria provided, single submitter clinical testing This sequence variant is a single nucleotide substitution (C>T) at coding position 5560 of the CHD3 gene that results in an arginine to tryptophan amino acid change at residue 1854 of the CHD3 protein. The Arg1854 residue falls within a region of the protein that is important for interaction with the pericentrin protein and affects its chromatin remodeling activity. This is a de novo, novel variant that has not been previously reported in variant (ClinVar) or population (gnomAD) databases, to our knowledge. Bioinformatic tools predict that this variant would be damaging, and the Arg1854 residue is highly conserved across the vertebrate species examined. Functiol studies testing the effect of this variant on protein structure or activity have not been performed, to our knowledge. Given the currently available evidence, we consider this variant likely pathogenic. ACMG Criteria: PM2, PP3, PS2
