RCV001042052 | SCV001205711 | uncertain significance | not provided | 2024-01-19 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 537 of the COL9A1 protein (p.Thr537Met). This variant is present in population databases (rs141895443, gnomAD 0.1%). This variant has not been reported in the literature in individuals affected with COL9A1-related conditions. ClinVar contains an entry for this variant (Variation ID: 840134). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The methionine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |

Ambry Genetics | RCV003160283 | SCV003876419 | uncertain significance | Inborn genetic diseases | 2023-02-28 | criteria provided, single submitter | clinical testing | The c.1610C>T (p.T537M) alteration is located in exon 23 (coding exon 23) of the COL9A1 gene. This alteration results from a C to T substitution at nucleotide position 1610, causing the threonine (T) at amino acid position 537 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
