Labcorp Genetics (formerly Invitae), Labcorp RCV002009159 SCV002272762 uncertain significance Brachyolmia-amelogenesis imperfecta syndrome 2022-08-16 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 1488414). This variant has not been reported in the literature in individuals affected with LTBP3-related conditions. This variant is present in population databases (rs746544643, gnomAD 0.003%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 144 of the LTBP3 protein (p.Ala144Val).
