Likely benign, criteria provided, single submitter | clinical testing | KCCC/NGS Laboratory, Kuwait Cancer Control Center | Jul 07, 2023 | - - |
Benign, criteria provided, single submitter | clinical testing | Myriad Genetics, Inc. | Jun 05, 2024 | This variant is considered benign. Homozygosity has been confirmed in one or more individuals. As homozygosity for pathogenic variants in this gene is generally assumed to result in embryonic lethality, this variant is unlikely to be pathogenic. This variant has been observed at a population frequency that is significantly greater than expected given the associated disease prevalence and penetrance. - |

Hereditary cancer-predisposing syndrome Benign:1
Likely benign, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 13, 2017 | This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. - |
