Use to confirm a diagnosis of maturity-onset diabetes of the young (MODY) or neonatal diabetes (ND) in a symptomatic individual. Use as predictive diagnostic or carrier testing in individuals with a family history of MODY or ND.
Variant Interpretation:
What is the protocol for interpreting a variation as a VUS?
Help
Multiple methodologies are utilized to classify a VUS. General knowledge regarding the gene and types of disease-associated mutations is reviewed. Population frequency is used to determine the incidence in which the variant is present in the general population as well as in specific ethnicities. Computational prediction programs are used to … View more

Are family members with defined clinical status recruited to assess significance of VUS without charge?
Help
Yes.
Yes.
Will the lab re-contact the ordering physician if variant interpretation changes?
Help
Yes. For significant changes to variant classification, an amended report is sent to the ordering facility and ARUP Laboratories will attempt to contact the provider. Clinicians are encouraged to continue to analyze the literature and re-contact the laboratory if a reclassification may be warranted.

Analytical Validity:
Help
The analytical sensitivity is approximately 99 percent for single nucleotide variants (SNVs) and greater than 93 percent for insertions/duplications/deletions from 1-10 base pairs in size. Variants greater than 10 base pairs may be detected, but the analytical sensitivity may be reduced.
Assay limitations:
Help
The following regions are not sequenced due to technical limitations of the assay:
CEL (NM_001807) exons 1, 8, 9, 11
ABCC8 (NM_001351295) partial exon 14 (Chr11:17449973-17450018)

Software used to interpret novel variations
Help
The software utilized varies depending on the gene and variant type. Some examples of computational prediction programs ARUP Laboratories uses are SIFT, Polyphen2, Mutation Taster, NetGene and NNSplice. The evidence of pathogenicity generated by these computer prediction programs is considered weak.
Laboratory's policy on reporting novel variations Help
ARUP Laboratories complies with New York regulations for all variants reported. If a VUS is incidentally detected using a mutation panel or in an ACMG-recommended gene via exome sequencing, it will not be reported (in agreement with ACMG recommendations for standards for interpretation and reporting of sequence variations). Please see … View more
