Invitae | RCV000813221 | SCV000953568 | uncertain significance | Severe early-onset pulmonary alveolar proteinosis due to MARS deficiency; Charcot-Marie-Tooth disease axonal type 2U | 2018-12-10 | 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. The current clinical and genetic evidence is not sufficient to establish whether loss-of-function variants in MARS cause disease. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with MARS-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change affects an acceptor splice site in intron 14 of the MARS gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. |
