The most common molecular defects associated with MODY are in the GCK, HNF1A, HNF4A and HNF1B genes. About 80% of individuals with MODY will have a mutation in one of the 4 genes listed above. See table on page 2 for summary frequency of genes related to MODY along with … View more

It is estimated that about 1-2% of individuals with diabetes have a primary insulin secretion defect relatedto MODY. Features indicative of MODY include hyperglycemia diagnosed before the age of 25, a family history consistent with autosomal dominant inheritance of diabetes, significant C-peptide levels, and absence of obesity (Vaxillaire et al. … View more

Variant Interpretation:
What is the protocol for interpreting a variation as a VUS? Help
Our lab has created a variant classification system which is based on the American College of Medical Genetics and Genomics guidelines (Genet Med. 2015 May;17(5):405-24).

Are family members with defined clinical status recruited to assess significance of VUS without charge? Help

Will the lab re-contact the ordering physician if variant interpretation changes? Help
Yes. Ordering physician will be notified by mail, fax or email with updated information for variant.
