Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces histidine with glutamine at codon 47 of the LRRC10 protein (p.His47Gln). The histidine residue is weakly conserved and there is a small physicochemical difference between histidine and glutamine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with LRRC10-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. -
