Description

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 missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). This missense change has been observed in individual(s) with clinical features of TMEM38B and/or osteogenesis imperfecta (Invitae; Inviate). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs765078943, gnomAD 0.005%). This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 112 of the TMEM38B protein (p.Leu112Pro).
