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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -3 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.19932336).

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000026 (38/1461874) while in subpopulation SAS AF = 0.00029 (25/86258). AF 95% confidence interval is 0.000201. There are 1 homozygotes in GnomAdExome4. There are 23 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
