Laboratory Services

UMMC Medical Genetics specialists offer comprehensive evaluation and treatment for known or suspected inherited disorders including:


Testing can be performed on blood, bone marrow, amniotic fluid, or solid tissue. Tissue culture and cryopreservation are also available.

  • FISH (fluorescent in-situ hybridization diagnostics testing) for certain syndromes (e.g., Angelman, cri-du-chat, DiGeorge (22q- or velocardiofacial), Kallman, Miller-Dieker, Prader-Willi, retinoblastoma, Smith-Magenis, Williams and Wolf-Hirschhorn)
  • FISH for oncological/hematological disorders
  • High-resolution chromosome banding

Biochemical genetics

  • Biotinidase measurement
  • Carbohydrate deficient transferring studies
  • Cerebrospinal fluid amino acid and neurotransmitter analysis
  • G-6-PD quantification
  • Lysosomal enzyme measurements
  • Plasma amino acid analysis
  • Plasma carnitine level and acylcarnitine profile
  • Plasma lactate and pyruvate quantification
