Labcorp Genetics (formerly Invitae), Labcorp RCV000761211 SCV004521609 uncertain significance Left ventricular noncompaction 1 2024-11-18 criteria provided, single submitter clinical testing This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 49 of the DTNA protein (p.Asn49Ser). This variant is present in population databases (rs775975702, gnomAD 0.0009%). This missense change has been observed in individual(s) with left ventricular noncompaction cardiomyopathy (PMID: 29118297). ClinVar contains an entry for this variant (Variation ID: 623092). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects DTNA function (PMID: 29118297). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
