RCV001089942 | SCV001244987 | uncertain significance | Nephrotic syndrome | 2018-08-04 | criteria provided, single submitter | clinical testing | A heterozygous missense variant, NM_005245.3(FAT1):c.10481A>G, has been identified in exon 18 of 27 of the FAT1 gene. The variant is predicted to result in a minor amino acid change from glutamine to arginine at position 3494 of the protein (NP_005236.2(FAT1):p.(Gln3494Arg)). The glutamine at this position has low conservation (100 vertebrates, UCSC), and is located within the cadherin repeat domain. In silico predictions of pathogenicity for this variant are conflicting (Polyphen, SIFT, CADD, Mutation Taster). The variant is present in the gnomAD database at a frequency of 0.0008% (0 homozygotes). This variant has not been previously reported in clinical cases. Analysis of parental samples indicated this variant was maternally inherited. Based on the information available at the time of curation, this variant has been classified as a VARIANT of UNCERTAIN SIGNIFICANCE (VUS). |
