Episodes of unresponsiveness lasting seconds can later give way to myoclonic jerks; ADGRV1 emerges as a susceptibility gene, with EEG traits seen in unaffected relatives.

Jerks that strike soon after waking, often with tonic-clonic or absence seizures, start in adolescence; EEG, TMS and genetic testing for JME7 are described.

Myoclonic seizures that start in adolescence, the GJD2 T allele link and what genetic testing for JME can offer families, including SUDEP risk research.

Low AMP deaminase activity shortens red blood cell lifespan and can cause hemolytic anemia; enzyme assays and AMPD3 testing identify affected people and carriers.

Discover the role of genetic testing in diagnosing Familial Ectopia Lentis, guiding treatment decisions, and improving surgical outcomes for better vision.

Exome and next-generation sequencing have named pathogenic variants in affected relatives, informing monitoring, medication, defibrillator and reproductive decisions.

Markers at this chromosomal region influence fasting glucose levels and can be read through whole-genome sequencing or targeted genotyping as part of risk work.
