Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_152686.4(DNAJC18):c.1063C>T(p.Arg355Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000354 in 1,612,408 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R355H) has been classified as Uncertain significance.
