Variant summary

Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_Strong BP6_Very_Strong BA1

The NM_001378609.3(OTOGL):c.6247A>G(p.Ile2083Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.929 in 1,505,062 control chromosomes in the GnomAD database, including 649,613 homozygotes. In-silico tool predicts a benign outcome for this variant. 12/16 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I2083T) has been classified as Uncertain significance.

Genes affected

OTOGL (HGNC:26901): (otogelin like) The protein encoded by this gene belongs to the otogelin family. This gene is expressed in the inner ear of vertebrates with the highest level of expression seen at the embryonic stage and lowest in adult. Knockdown studies in zebrafish suggest that this gene is essential for normal inner ear function. Mutations in this gene are associated with autosomal recessive deafness.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=6.47368E-7).
• BP6: Variant 12-80358880-A-G is Benign according to our data. Variant chr12-80358880-A-G is described in ClinVar as [Benign]. Clinvar id is 226966.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr12-80358880-A-G is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.977 is higher than 0.05.

Benign, criteria provided, single submitter	clinical testing	GeneDx	May 09, 2017	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Nov 11, 2015	Ile2074Val in exon 51 of OTOGL: This variant is not expected to have clinical si gnificance because it has been identified in 7.6% (641/8456) of European America n chromosomes from a broad population by the NHLBI Exome Sequencing Project (htt p://evs.gs.washington.edu/EVS; dbSNP rs2034528). -
