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 made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.4228553).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000329 (5/152106) while in subpopulation NFE AF= 0.0000735 (5/68006). AF 95% confidence interval is 0.0000285. There are 0 homozygotes in gnomad4. There are 0 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Feb 17, 2024

The c.220C>A (p.P74T) alteration is located in exon 1 (coding exon 1) of the LRIG2 gene. This alteration results from a C to A substitution at nucleotide position 220, causing the proline (P) at amino acid position 74 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
