Genetics Consult

This week's theme is "von." Whatever that means.
You are on the genetics consult service (you're at a tertiary care hospital) and are asked to see a 6 month old infant with seizure. Physical exam shows a protruding abdomen and hepatomegaly. Laboratory tests show hypoglycemia, hyperlipidemia, and a lactic acidosis. The infant was born to a healthy G1P0 30 year old mother but since birth has had poor growth. The pattern of inheritance is shown above.

Challenge: Given that this is "von" week, what's the diagnosis?
