Clinical Genomics Laboratory, Washington University in St. Louis RCV004560387 SCV005047086 uncertain significance Lymphatic malformation 6 2024-02-05 criteria provided, single submitter clinical testing A PIEZO1 c.2578G>A (p.Val860Met) variant was identified at a heterozygous allelic fraction of 50.6%, a frequency which may be consistent with germline origin. This variant has been reported in a patient with hereditary spherocytosis (Mansour-Hendili L et al., PMID: 32641076). It is only observed on 100/1,549,866 alleles in the general population (gnomAD v.4.0.0), indicating it is not a common variant. Computational predictors suggest that the variant does not impact PIEZO1 function. Due to limited information, and based on ACMG/AMP guidelines for variant interpretation (Richards S et al., PMID: 25741868), the clinical significance of this variant is uncertain at this time.
