Submissions by phenotype
not provided Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Oct 02, 2023 | Has not been previously published as pathogenic or benign to our knowledge; Not observed at significant frequency in large population cohorts (gnomAD); Initiation codon variant in a gene for which loss of function is a known mechanism of disease - |
Ehlers-Danlos syndrome, musculocontractural type Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Aug 10, 2023 | This variant is not present in population databases (gnomAD no frequency). This sequence change affects the initiator methionine of the CHST14 mRNA. The next in-frame methionine is located at codon 44. This variant has not been reported in the literature in individuals affected with CHST14-related conditions. ClinVar contains an entry for this variant (Variation ID: 2004232). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. 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. - |
