Variant summary
Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS2
The NM_014008.5(CCDC22):c.659G>A(p.Arg220Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000227 in 1,202,312 control chromosomes in the GnomAD database, with no homozygous occurrence. There are 84 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R220W) has been classified as Uncertain significance.
