Broad Center for Mendelian Genomics, Broad Institute of MIT and Harvard RCV001004905 SCV001164405 uncertain significance Elliptocytosis 2; Hereditary spherocytosis type 2 2018-12-03 criteria provided, single submitter research The heterozygous p.Leu49Phe variant in SPTA1 was identified by our study, with a likely pathogenic variant associated with spherocytosis, in one individual with elliptocytosis and spherocytosis. This variant was absent from large population studies and OMIM has reported this variant as Pathogenic in ClinVar (Variation ID: 12851). Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In vitro functional studies and some computational tools provide some evidence that the p.Leu49Phe variant may impact protein function by affecting helical formation and tetramer binding (PMID: 18218854, 19593814, 18783249). However, these types of assays may not accurately represent biological function. In summary, although there is some suspicion for pathogenicity, the clinical significance of the p.Leu49Phe is uncertain. ACMG/AMP Criteria applied: PM2, PS3_Moderate (Richards 2015).
