IMAGe syndrome
|
Very rare. Acronym for Intrauterine growth retardation, Metaphyseal dysplasia, congenital Adrenal hypoplasia, Genital anomalies. Autosomal dominant transmission of a pathogenic variant of the CDKN1C gene on 11p15.4. The disease develops only if the gene is of maternal origin.
Different aspects:
- facial dysmorphism: frontalbossing, low set ears, broad nasal bridge; sometimes triangular facies with micrognathia; rarely: cleft palate (or bifid uvula)
- short stature: intrauterine and postnatal growth retardation
- metaphyseal dysplasia: short limbs, osteopenia; sometimes early scoliosis
- adrenal insufficiency: Addisonian crisis [hypoNa, hyperK, hypoglycemia, hypotension] during the first month of life, sometimes later
- genital anomalies: micropenis, cryptorchidism, hypospadias
Anesthetic implications:
adapt the substitution dose of cortisone ; short stature; risk of difficult mask ventilation and intubation in case of micrognathia
