Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 1P and 2B. PP2BP4BP6
The NM_080680.3(COL11A2):c.3725C>T(p.Ser1242Leu) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000936 in 1,612,882 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). Synonymous variant affecting the same amino acid position (i.e. S1242S) has been classified as Likely benign.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Oct 26, 2017 | The p.Ser1242Leu variant in COL11A2 has been previously reported by our laborato ry in one individual with hearing loss due to an alternate etiology. It has also been reported in ClinVar (Variation ID#356389) as likely benign in individuals of unknown clinical status. This variant has been identified in 34/271854 total chromosomes across several populations by the Genome Aggregation Database (gnomA D, http://gnomad.broadinstitute.org; dbSNP rs534570825). Although this variant h as been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summa ry, the clinical significance of the p.Ser1242Leu variant is uncertain. ACMG/AMP Criteria applied: BP5, PM2_P (Richards 2015). - |
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 22, 2021 | The c.3725C>T (p.S1242L) alteration is located in exon 51 (coding exon 51) of the COL11A2 gene. This alteration results from a C to T substitution at nucleotide position 3725, causing the serine (S) at amino acid position 1242 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
Otospondylomegaepiphyseal dysplasia, autosomal recessive Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Jan 13, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease. - |
