Rubinstein-taybi syndrome with psychosis

Area of Science:

• Genetics
• Psychiatry
• Developmental Biology

Background:

• Rubinstein-Taybi syndrome (RTS) is a rare genetic disorder associated with distinctive physical features, developmental delays, and behavioral issues.
• Existing literature lacks comprehensive data on the co-occurrence of psychosis, specifically schizophrenia or non-affective psychosis, in individuals with RTS.

Observation:

• This report details two cases of patients diagnosed with Rubinstein-Taybi syndrome who also presented with comorbid psychotic disorders.
• One patient was diagnosed with paranoid schizophrenia, and the other with psychosis, possibly schizophrenia.

Findings:

• The study suggests a potential association between Rubinstein-Taybi syndrome and the development of schizophrenia or non-affective psychosis.
• While genetic analysis was not performed, potential shared etiological factors involving RNA polymerase II regulators and hypoxia-inducible factor 1 alpha (HIF1A) are discussed.

Implications:

• These findings indicate that schizophrenia and non-affective psychosis should be considered as potential comorbid psychiatric conditions in individuals with Rubinstein-Taybi syndrome.
• Further research into the genetic and molecular underpinnings of this association is warranted to improve diagnostic and therapeutic strategies.
