Invitae RCV000796187 SCV000935689 uncertain significance MYH-associated polyposis 2019-07-30 criteria provided, single submitter clinical testing This sequence change replaces serine with cysteine at codon 372 of the MUTYH protein (p.Ser372Cys). The serine residue is moderately conserved and there is a moderate physicochemical difference between serine and cysteine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MUTYH-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: Deleterious; PolyPhen-2: Benign; Align-GVGD: Class C1. The cysteine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. 5
Department of Pathology and Laboratory Medicine,Sinai Health System RCV000796187 SCV001551701 uncertain significance MYH-associated polyposis no assertion criteria provided clinical testing MUTYH, EXON12, c.1115C>G, p.Ser372Cys, Heterozygous, Uncertain Significance The MUTYH p.Ser372Cys variant was not identified in the literature nor was it identified in dbSNP or ClinVar. The variant was not identified in the following control databases: the Exome Aggregation Consortium (August 8th 2016) or the Genome Aggregation Database (Feb 27, 2017). The p.Ser372 residue is not conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information, the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. Assessment Date: 2019/07/22.
