Aim: To present a case report of a patient with classic galactosemia and the Q188R/K285N GALT mutation, who conceived spontaneously twice despite severe ovarian failure. A review of the literature is included.
Materials And Methods: A 20-year-old patient with classic galactosemia and premature ovarian insufficiency (POI) came to our attention. We performed a routine hormonal and ultrasound examination confirming low ovarian reserve. Due to low rates of pregnancies in individuals with POI (5%-10%), we were almost certain of the infeasibility of pregnancy.
Results: Surprisingly, several months after hospitalization, the patient conceived without any medical intervention and less than a year after the first birth she became pregnant again. While reviewing the literature, 90 pregnancies among galactosemic patients were identified.
Conclusions: Ovarian failure is a long-term diet-independent complication of classic galactosemia, pertaining to about 90% of affected individuals. This case confirms its unpredicted course, as even the presence of unfavorable factors (absence of spontaneous puberty, early diagnosis of POI, undetectable AMH) may not preclude the chance for conception.

Purpose: Galactosemia is a rare inborn error of galactose metabolism. There are several forms, the most severe being classic galactosemia (CG), which begins in the first few days of life. Nowadays, it is possible to screen CG at birth, averting acute decompensation or death through diet.

Type III galactosemia is characterized by the inability to metabolize galactose due to deficiency of the UDP-galactose-4-epimerase (GALE) gene, which catalyzes the interconversion of UDP-Galactose and UDP-Glucose. Additionally, GALE interconverts UDP-N-Acetylgalactosamine and UDP-N-Acetylglucosamine. These four sugars are needed for glycosylation of biomolecules.
