Lurie Children's Hospital of ChicagoMar 30, 2021SYNPO2L NM_001114133.2 exon 4 p.Pro708Serfs*13 (c.2120dup): This variant has not been reported in the literature and is not present in large control databases. Evolutionary conservation and computational predictive tools for this variant are limited or unavailable. This variant is a duplication of 1 cytosine nucleotide in a string of 7 cytosines and is predicted to create a premature stop codon 13 amino acids downstream from this location which results in an absent or abnormal protein. However, there is insufficient evidence to establish loss of function (LOF) as a known mechanism of disease. In addition, this variant occurs within the last exon of this gene; due to its position, it is possible that this protein may escape nonsense mediated decay. Further studies are needed to understand its impact. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
