We are proud to announce the newest addition to our staff, Dr. Daniela del Gaudio.  Dr. del Gaudio received her PhD. in Clinical Molecular Biology from the University of Naples “Federico II”, Naples, Italy.  Shortly after graduation, Dr. del Gaudio joined American Board of Medical Genetics training program at Baylor College of Medicine and became certified in Clinical Molecular Genetics.  Prior to joining The University of Chicago Genetic Services, Dr.

We are now offering testing for 7 genes associated with autosomal recessive microcephaly.  Autosomal recessive primary microcephaly (MCPH) is characterized by:

Patients with Kabuki syndrome have characteristic facial features, short stature, congenital heart defects, skeletal anomalies, immunological abnormalities, and mild to moderate mental retardation. Facial features include long palpebral fissures with eversion of the lower lateral eyelid, sparse and arched eyebrows, depressed nasal tip, and large prominent earlobes. Other features include joint laxity, dental abnormalities, fingertip pads, and renal/urinary tract anomalies.

The University of Chicago Genetic Services is excited to be starting a monthly newsletter to keep our clients informed about our laboratory. We'll use this forum to inform you about the latest testing in our laboratory and any changes in our services. This newsletter should be a great way for us to let you know about great new tests in our laboratory that may really impact your clinical service.  We'll also spotlight members of our incredible staff to help you put faces with the names of our expertise. 

Glucose transporter type 1 deficiency syndrome (GLUT1DS) is characterized by infantile-onset epileptic encephalopathy associated with delayed development, acquired microcephaly, motor incoordination, and spasticity.  Seizures typically begin within the first 4 months of life following a normal birth and gestation.   Glucose concentration in cerebrospinal fluid should be the first test considered in patients suspected of having GLUT1DS.  Hypoglycorrhachia (low CSF glucose, less than 40mg/dl) is practically diagnostic for this disorder.  Mutations of the Solute Carrier Family 2, Member 1

We are now offering testing for the 3 known genes for Centronuclear/Myotubular Myopathy, MTM1, DNM2, and BIN1. 

We are  now offering full gene sequencing of the CASK gene.  Mutations in CASK have been reported in:

• females with X-linked mental retardation and microcephaly with pontine and cerebellar hypoplasia.  These mutations are typically de novo and thought to be lethal in males.
• males with mild to moderate MR with or without nystagmus.  These mutations are typically familial and carrier females are unaffected.
