Labcorp Genetics (formerly Invitae), Labcorp RCV001509085 SCV005716031 pathogenic not provided 2024-06-13 criteria provided, single submitter clinical testing This variant, c.464_466dup, results in the insertion of 1 amino acid(s) of the SPTA1 protein (p.Leu155dup), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs749754226, gnomAD 0.007%). This variant has been observed in individuals with autosomal dominant hereditary elliptocytosis and autosomal recessive hereditary pyropoikilocytosis (PMID: 8790144, 30393954). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 1163758). Algorithms developed to predict the effect of variants on gene product structure and function are not available or were not evaluated for this variant. Experimental studies have shown that this variant affects SPTA1 function (PMID: 3922449). For these reasons, this variant has been classified as Pathogenic.
