ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories RCV003120152 SCV003799806 uncertain significance not provided 2022-06-30 criteria provided, single submitter clinical testing The PIEZO1 c.4556A>C; p.Gln1519Pro variant (rs767365106) is reported in the literature in individuals affected with hereditary xerocytosis (Picard 2019) or hydrops fetalis (Al-Kouatly 2021), but without clear association with disease. This variant is found in the general population with an overall allele frequency of 0.037% (67/181532 alleles) in the Genome Aggregation Database. The glutamine at codon 1519 is weakly conserved, and computational analyses are uncertain whether this variant is neutral or deleterious (REVEL: 0.560). Due to limited information, the clinical significance of this variant is uncertain at this time. References: Al-Kouatly HB et al.
