Brachyolmia recessive type is a form of brachyolmia with characteristics of short-trunked short stature with platyspondyly and scoliosis. Corneal opacities and precocious calcification of the costal cartilage are rare syndromic components. Premature pubarche may occur. Mental status and facies are reported to be normal. Some patients are reported to have peripheral punctuate opacities in the cornea found on slit lamp examination (formerly Toledo type). A number of different mutations in the PAPSS2 gene (10q23.2-q23.3) have been reported in affected patients. PAPPS2 encodes PAPS (3'-phosphoadenosine 5'-phosphosulfate) synthase 2. Observed to follow an autosomal recessive pattern of inheritance. |

A rare congenital isolated hyperinsulinism disorder with characteristics of neonatal presentation of severe refractory hypoglycemia in the first two days of life with limited response to medical management sometimes requiring pancreatic resection. Newborns are often large for gestational age with mild to moderate hepatomegaly and diffuse form of hyperinsulinism due to Kir6.2 deficiency. Persistent hypoglycemia, hyperglycemia and type 1 diabetes mellitus may develop later in life. Life-threatening hypoglycemic coma or status epilepticus have also been associated. Caused by mutation in the gene encoding the Kir6.2 subunit of the inwardly rectifying potassium channel (KCNJ11). |
