Maternal PKU Syndrome Fetal Risk Calculator

Calculates fetal risk in maternal phenylketonuria based on maternal blood phenylalanine levels, timing of metabolic control, and gestational age, estimating risk of microcephaly, CHD, and intellectual disability.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates fetal risk in maternal phenylketonuria based on maternal blood phenylalanine levels, timing of metabolic control, and gestational age, estimating risk of microcephaly, CHD, and intellectual disability

Each component has a specific meaning:

  • Maternal blood phenylalanine levels — The maternal blood phenylalanine levels recorded for the scenario being assessed.
  • Timing of metabolic control — The timing of metabolic control recorded for the scenario being assessed.
  • Gestational age — The gestational age recorded for the scenario being assessed.
  • Estimating risk of microcephaly — The estimating risk of microcephaly recorded for the scenario being assessed.
  • CHD — The chd recorded for the scenario being assessed.
  • Intellectual disability — The intellectual disability recorded for the scenario being assessed.

Note: Interpret the maternal pku risk result against the thresholds and context described above.

How to Use

Enter the maternal blood phenylalanine levels, timing of metabolic control, gestational age, estimating risk of microcephaly, CHD, intellectual disability for the scenario you are assessing. Calculates fetal risk in maternal phenylketonuria based on maternal blood phenylalanine levels, timing of metabolic control, and gestational age, estimating risk of microcephaly, CHD, and intellectual disability. Use the maternal pku risk result to inform your calculation.
