List of Latin-script trigraphs
A number of trigraphs are found in the Latin script, most of these used especially in Irish orthography.
A
⟨aai⟩ is used in Dutch to write the sound /aːi̯/.
⟨abh⟩ is used in Irish to write the sound /əu̯/, or in Donegal, /oː/, between broad consonants.
⟨adh⟩ is used in Irish to write the sound /əi̯/, or in Donegal, /eː/, between broad consonants, or an unstressed /ə/ at the end of a word.
⟨aei⟩ is used in Irish to write the sound /eː/ between a broad and a slender consonant.
⟨agh⟩ is used in Irish to write the sound /əi̯/, or in Donegal, /eː/, between broad consonants.
⟨aim⟩ is used in French to write the sound /ɛ̃/ (/ɛm/ before a vowel).
⟨ain⟩ is used in French to write the sound /ɛ̃/ (/ɛn/ before a vowel). It also represents /ɛ̃/ in Tibetan Pinyin, where it is alternatively written än.
⟨aío⟩ is used in Irish to write the sound /iː/ between broad consonants.
⟨amh⟩ is used in Irish to write the sound /əu̯/, or in Donegal, /oː/, between broad consonants.
Glycine encephalopathy
Glycine encephalopathy (also known as non-ketotic hyperglycinemia or NKH) is a rare autosomal recessive disorder of glycine metabolism. After phenylketonuria, glycine encephalopathy is the second most common disorder of amino acid metabolism. The disease is caused by defects in the glycine cleavage system, an enzyme responsible for glycine catabolism. There are several forms of the disease, with varying severity of symptoms and time of onset. The symptoms are exclusively neurological in nature, and clinically this disorder is characterized by abnormally high levels of the amino acid glycine in bodily fluids and tissues, especially the cerebral spinal fluid.
Glycine encephalopathy is sometimes referred to as "nonketotic hyperglycinemia" (NKH), as a reference to the biochemical findings seen in patients with the disorder, and to distinguish it from the disorders that cause "ketotic hyperglycinemia" (seen in propionic acidemia and several other inherited metabolic disorders). To avoid confusion, the term "glycine encephalopathy" is often used, as this term more accurately describes the clinical symptoms of the disorder.
