The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 32)
• Consequence: RESF1 NM_018169.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.29

Genes affected

RESF1 (HGNC:25559): (retroelement silencing factor 1) Predicted to enable histone binding activity and histone methyltransferase binding activity. Predicted to be involved in negative regulation of single stranded viral RNA replication via double stranded DNA intermediate and positive regulation of DNA methylation-dependent heterochromatin assembly. Predicted to act upstream of or within response to bacterium. Predicted to be located in nucleus. Predicted to colocalize with gamma-tubulin complex.
