The variant allele was found at a frequency of 0.0493 in 152,198 control chromosomes in the GnomAD database, including 609 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.049 (609 hom., cov: 33)
• Consequence: LRIG1 NM_015541.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -4.49

Genes affected

LRIG1 (HGNC:17360): (leucine rich repeats and immunoglobulin like domains 1) Predicted to act upstream of or within several processes, including innervation; otolith morphogenesis; and sensory perception of sound. Predicted to be located in plasma membrane. Predicted to be active in extracellular matrix and extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.
