name: Rubinstein-Taybi syndrome due to 16p13.3 microdeletion

description: Chromosome 16p13.3deletion syndrome is a chromosome abnormality that can affect many parts of the body. People with this condition are missing a small piece (deletion) of chromosome 16 at a location designated p13.3. Although once thought to be a severe form of Rubinstein-Taybi syndrome, it is now emerging as a unique syndrome. Signs and symptoms may include failure to thrive, hypotonia (reduced muscle tone), short stature, microcephaly (unusually small head), characteristic facial features, mild to moderate intellectual disability, organ anomalies (i.e. heart and/or kidney problems), and vulnerability to infections. Chromosome testing of both parents can provide information about whether the deletion was inherited. In most cases, parents do not have any chromosome abnormalities. However, sometimes one parent has a balanced translocation where a piece of a chromosome has broken off and attached to another one with no gain or loss of genetic material. The balanced translocation normally does not cause signs or symptoms, but it increases the risk for having a child with a chromosome abnormality like a deletion. Treatment is based on the signs and symptoms present in each person.To learn more about chromosome abnormalities in general, view our GARD fact sheet on Chromosome Disorders.

GTP cyclohydrolase I deficiency encompasses a spectrum of disease that includes autosomal dominant and autosomal recessive forms, with severity correlating with the residual enzyme activity. Individuals who are heterozygous for pathogenic variants in GCH1 have symptoms ranging from none (due to reduced penetrance) to dopa-responsive dystonia, which is the most common presentation in symptomatic cases, to rarer neurological presentations such as adult-onset "benign" parkinsonism, various types of focal dystonia, and symptoms simulating cerebral palsy or spastic paraplegia. Hyperphenylalaninemia is absent, and patients respond well to treatment with levodopa. Individuals who are homozygous or compound heterozygous for pathogenic variants in GCH1 typically present with hyperphenylalaninemia, often identified by newborn screening, and severe neurological features and due to very low or undetectable enzyme activity. Treatment with levodopa, BH4, and 5-hydroxytryptophan can improve the symptoms but does not prevent development of severe encephalopathy. Rare cases of GTP cyclohydrolase I deficiency with a phenotype that is intermediate in severity between dopa-responsive dystonia and the severe autosomal recessive form have also been described, supporting the existence a phenotypic spectrum of disease.
