Ambry Genetics | RCV002916017 | SCV003658623 | uncertain significance | Inborn genetic diseases | 2022-11-01 | criteria provided, single submitter | clinical testing | The c.3142A>G (p.T1048A) alteration is located in exon 15 (coding exon 14) of the COL12A1 gene. This alteration results from a A to G substitution at nucleotide position 3142, causing the threonine (T) at amino acid position 1048 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |

RCV003420467 | SCV004109725 | uncertain significance | COL12A1-related disorder | 2023-05-01 | criteria provided, single submitter | clinical testing | The COL12A1 c.3142A>G variant is predicted to result in the amino acid substitution p.Thr1048Ala. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |

RCV003777944 | SCV004591437 | uncertain significance | Ullrich congenital muscular dystrophy 2; Bethlem myopathy 2 | 2022-12-02 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt COL12A1 protein function. This variant has not been reported in the literature in individuals affected with COL12A1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 1048 of the COL12A1 protein (p.Thr1048Ala). |
