[Merge] MONDO:0016022 'early myoclonic encephalopathy'

[nicolevasilevsky]

Merge Mondo term (ID and Label)
MONDO:0016022 'early myoclonic encephalopathy'

Into:
MONDO:0800491 'early-infantile DEE'.

Suggested revision and reasons
According to ILAE:
"Early-infantile developmental and epileptic encephalopathy syndrome (EIDEE) is characterized by frequent drug-resistant seizures that begin ≤3 months of age, with abnormal interictal EEG and neurological examination. This syndrome encompasses the previous syndromes of Ohtahara syndrome and early myoclonic encephalopathy. Treatable metabolic etiologies (especially pyridoxine and pyridoxal-5-phosphate disorders) should be excluded early."

Note - do not add to list until we've discussed this at the epilepsy workshop on Jan 17, 2025

We discussed this at the workshop and it was suggested that I follow up with Elaine Wirrell, I emailed her on 2025-02-05.

If we don't hear back, I think it's okay to proceed with this as proposed based on ILAE.

Additional tasks:

• exclude superclass (MONDO:0016022 'early myoclonic encephalopathy') from 'familial infantile myoclonic epilepsy' and 'myoclonic epilepsy, Hartung type'
  • reclassify both as a child of new term 'myoclonic epilepsy' (Request for new term [Myoclonic epilepsy] #8602)

(if I hear back from Eileen, ask her if these should be children of 'early infantile DEE' but based on OMIM descriptions, they do not seem like DEEs)

[nicolevasilevsky]

• we had previously obsoleted MONDO:0016021 early infantile epileptic encephalopathy (per [Merge] MONDO_0016021 'early infantile epileptic encephalopathy' and MONDO_0100062 'developmental and epileptic encephalopathy' #2027), so I will point this obsolete class to MONDO:0800491 'early-infantile DEE'
