The ZNF827 c.2153delC (p.Pro718GlnfsTer12) variant is a frameshift variant that is expected to result in an absent or prematurely truncated protein product. A literature search was conducted for the gene, cDNA change, and amino acid change. No publications were identified through this search. This variant is absent from version 2.1.1 and version 3.1.1 of the Genome Aggregation Database despite its location in a region of good sequencing coverage, which suggests the variant is rare. Based on the available evidence, the p.Pro718GlnfsTer12 variant is classified as a variant of uncertain significance. -
