Two missense mutations were also found, mainly in exon 2 and exon 7. In addition, a common non-synonymous single nucleotide polymorphism in exon 12 was also identified. The presence of various CTH mutations is consistent with the various categories associated with cystathioninuria. Diagnosis
The main way to diagnosis cystathioninuria is simply through increased urinary excretion of cystathionine. In some cases, a genetic test is employed. Treatment
The treatment, if any is available, varies depending on the category of cystathioninuria a patient has. The vitamin B6 – responsive form is best treated by an increased consumption of vitamin B6. This increased consumption helps with cystathionases altered ability to bind to the active form of vitamin B6. References

DSM-5 has taken out the "culture–bound syndrome" language and replaced it with more "sensitive" language, and the glossary where the now shortened list of previously recognized culture–bound syndromes is titled "Other Specified" and "Unspecified" dissociative disorders. A more general discussion, involving the formation of a cultural identity, explanation, and assessment, has been added. In popular culture
William S. Burroughs mentions latah several times in his 1959 novel Naked Lunch, "a parody of modern mass man under modern conditioning programmes of advertising and public[ly] induced morality", according to Eric Mottram. Burroughs described latah as involving echopraxia, as well as being forcibly induced rather than spontaneously occurring. Latah is also mentioned in Burroughs 1963 novel The Yage Letters. Possible causes
The onset of latah is often associated with stress. In a study done by Tanner and Chamberland in 2001, a significant number of research participants had experienced a life stressor (such as a child or husband dying) just before becoming latah. Additionally, a large number of participants from many research studies have reported strange dreams occurring just before the onset of latah. These dreams usually had a sexual element to them, often involving penises. According to Tanner and Chamberland, perhaps the dreams, although with variation, indicate some sort of dysfunction in a specific anatomical area. Exploring this further might lead to more insights as to the cause and/or cure of latah. : 526–529  Osborne (2001) states that latah is a possible emotional outlet in a stifling culture.
