DCAF8-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesMay 16, 2023The DCAF8 c.959C>T variant is predicted to result in the amino acid substitution p.Ser320Leu. This variant occurs at the terminal nucleotide of an exon and is predicted to have a minor impact on splicing at the consensus splice site (Alamut Visual Plus v.1.6.1). However, these prediction programs are not equivalent to functional evidence. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0038% of alleles in individuals of Latino descent in gnomAD (http://gnomad.broadinstitute.org/variant/1-160206925-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
