RCV000768266 | SCV000898830 | uncertain significance | Neuronal ceroid lipofuscinosis 7; Macular dystrophy with central cone involvement | 2021-03-30 | criteria provided, single submitter | clinical testing | MFSD8 NM_152778 exon 2 p.Ala2Val (c.5C>T): This variant has not been reported in the literature and is not present in large control databases. Evolutionary conservation and computational predictive tools for this variant are unclear. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. |

RCV002536600 | SCV002965253 | uncertain significance | Neuronal ceroid lipofuscinosis 7 | 2023-12-22 | criteria provided, single submitter | clinical testing | This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 2 of the MFSD8 protein (p.Ala2Val). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with MFSD8-related conditions. ClinVar contains an entry for this variant (Variation ID: 626139). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. |
