Genes affected

TENT4B (HGNC:30758): (terminal nucleotidyltransferase 4B) Enables guanylyltransferase activity and polynucleotide adenylyltransferase activity. Involved in several processes, including RNA metabolic process; negative regulation of telomere maintenance via telomerase; and regulation of mRNA stability. Located in cytoplasm and nucleolus. Part of TRAMP complex. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

May 01, 2024

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. -
