Genes affected
LRIG2 (HGNC:20889): (leucine rich repeats and immunoglobulin like domains 2) This gene encodes a transmembrane protein containing leucine-rich repeats and immunoglobulin-like domains. The encoded protein promotes epidermal growth factor signalling, resulting in increased proliferation. Its expression in the cytoplasm of glioma cells is correlated with poor survival. Mutations in this gene can cause urofacial syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 19, 2017This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Leu6Glnfs*97) in the LRIG2 gene. It is expected to result in an absent or disrupted protein product. This variant has not been reported in the literature in individuals with LRIG2-related disease. For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in LRIG2 are known to be pathogenic (PMID: 23313374). -
