Galactosemia Risk factors

The major risk factor for galactosemia is the presence of the defective gene(s).

Galactosemia is an inherited autosomal recessive disorder of galactose metabolism. Two defective alleles are necessary to manifest the condition.^[1]

• Children born to carrier parents harboring the gene(s) run the risk of developing galactosemia.
• Therefore, every child born to carrier parents has a 25% chance of developing the disorder.^[2]
