Invitae | RCV000000164 | SCV000775602 | uncertain significance | Brown-Vialetto-Van Laere syndrome 1 | 2019-12-18 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine with tryptophan at codon 132 of the SLC52A3 protein (p.Arg132Trp). The arginine residue is weakly conserved and there is a moderate physicochemical difference between arginine and tryptophan. This variant is present in population databases (rs267606684, ExAC 0.006%). This variant has been reported to segregate with Brown-Vialetto-Van Laere syndrome (BVVLS) in a single family (PMID: 2020633). ClinVar contains an entry for this variant (Variation ID: 141). Experimental studies have shown that this missense change leads to cellular mislocalization of the SLC52A3 protein (PMID: 22273710). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
