Ambry Genetics | RCV002317574 | SCV000851097 | uncertain significance | Inborn genetic diseases | 2016-06-24 | criteria provided, single submitter | clinical testing | The p.F192L variant (also known as c.576C>G), located in coding exon 6 of the MFSD8 gene, results from a C to G substitution at nucleotide position 576. The phenylalanine at codon 192 is replaced by leucine, an amino acid with highly similar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6501 samples (13002 alleles) with coverage at this position. This amino acid position is not well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
Invitae | RCV000803180 | SCV000943042 | uncertain significance | Neuronal ceroid lipofuscinosis 7 | 2022-10-17 | criteria provided, single submitter | clinical testing | This sequence change replaces phenylalanine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 192 of the MFSD8 protein (p.Phe192Leu). This variant is present in population databases (rs777020801, gnomAD 0.01%). 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: 589864). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt MFSD8 protein function. 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. |
