Variant summary
Our verdict is Likely benign. The variant received -3 ACMG points: 0P and 3B. BP4_ModerateBP6
The NM_080680.3(COL11A2):c.1489C>T(p.Arg497Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000051 in 1,568,910 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R497H) has been classified as Likely benign.

- -
Has not been previously published as pathogenic or benign to our knowledge; Reported in ClinVar as a variant of uncertain significance (ClinVar Variant ID# 228528; Landrum et al., 2016); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; This variant is associated with the following publications: (PMID: 26582918, 27535533) -
not specified Uncertain:1
The p.Arg497Cys variant in COL11A2 has not been previously reported in individua ls with hearing loss, but has been identified in 0.3% (2/658) Latino chromosomes and in 1/2354 African chromosomes by the Exome Aggregation Consortium (ExAC, ht tp://exac.broadinstitute.org). Although this variant has been seen in the genera l population, its frequency is not high enough to rule out a pathogenic role. Co mputational prediction tools and conservation analysis do not provide strong sup port for or against an impact to the protein. In summary, the clinical significa nce of the p.Arg497Cys variant is uncertain. -
Inborn genetic diseases Uncertain:1
The c.1489C>T (p.R497C) alteration is located in exon 14 (coding exon 14) of the COL11A2 gene. This alteration results from a C to T substitution at nucleotide position 1489, causing the arginine (R) at amino acid position 497 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
COL11A2-related disorder Uncertain:1
The COL11A2 c.1489C>T variant is predicted to result in the amino acid substitution p.Arg497Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.011% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
