Fryns syndrome is an autosomal recessive multiple congenital anomaly syndrome that is usually lethal in the neonatal period. Fryns (1987) reviewed the syndrome. Presentation
Usually associated with diaphragmatic hernia,
pulmonary hypoplasia,
imperforate anus,
micropenis,
bilateral cryptorchidism,
cerebral ventricular dilation,
camptodactyly,
agenesis of sacrum,
low-set ear. Cytogenetics
In a newborn boy thought to have Fryns syndrome, Clark and Fenner-Gonzales (1989) found mosaicism for a tandem duplication of 1q24-q31.2. They suggested that the gene for this disorder is located in that region. However, de Jong et al. (1989), Krassikoff and Sekhon (1990), and Dean et al. (1991) found possible Fryns syndrome associated with anomalies of chromosome 15, chromosome 6, chromosome 8 and chromosome 22, respectively. Thus, these cases may all represent mimics of the mendelian syndrome and have no significance as to the location of the gene for the recessive disorder.By array CGH, Slavotinek et al. (2005) screened patients with DIH and additional phenotypic anomalies consistent with Fryns syndrome for cryptic chromosomal aberrations. They identified submicroscopic chromosome deletions in 3 probands who had previously been diagnosed with Fryns syndrome and had normal karyotyping with G-banded chromosome analysis. Two female infants were found to have microdeletions involving 15q26.2 (see 142340), and 1 male infant had a deletion in band 8p23.1 (see 222400). Diagnosis
Prenatal Diagnosis:

Aymé, et al. (1989) reported prenatal diagnosis of Fryns syndrome by sonography between 24 and 27 weeks. Manouvrier-Hanu et al. (1996) described the prenatal diagnosis of Fryns syndrome by ultrasonographic detection of diaphragmatic hernia and cystic hygroma. The diagnosis was confirmed after termination of the pregnancy.
The convalescent stage begins when all clinical signs of illness have disappeared, and continues until the sedimentation rate returns to normal, usually at six to eight weeks after the onset of illness.Adult onset of Kawasaki disease is rare. The presentation differs between adults and children: in particular, it seems that adults more often have cervical lymphadenopathy, hepatitis, and arthralgia.Some children, especially young infants, have atypical presentations without the classic set of symptoms. Such presentations are associated with a higher risk of cardiac artery aneurysms. Cardiac
Heart complications are the most important aspect of Kawasaki disease, which is the leading cause of heart disease acquired in childhood in the United States and Japan. In developed nations, it appears to have replaced acute rheumatic fever as the most common cause of acquired heart disease in children. Coronary artery aneurysms occur as a sequela of the vasculitis in 20–25% of untreated children. It is first detected at a mean of 10 days of illness and the peak frequency of coronary artery dilation or aneurysms occurs within four weeks of onset. Aneurysms are classified into small (internal diameter of vessel wall <5 mm), medium (diameter ranging from 5–8 mm), and giant (diameter > 8 mm). Saccular and fusiform aneurysms usually develop between 18 and 25 days after the onset of illness.Even when treated with high-dose IVIG regimens within the first 10 days of illness, 5% of children with Kawasaki disease develop at the least transient coronary artery dilation and 1% develop giant aneurysms.
