Maternal phosphoglucomutase (PGM) phenotype is linked to reproductive success. Women with PGM Type 1 show associations with reduced fertility, increased abortion risk with age, and altered fetal growth.

Area of Science:

  • Human Genetics
  • Reproductive Biology
  • Biochemistry

Background:

  • The phosphoglucomutase (PGM) enzyme plays a role in carbohydrate metabolism.
  • Understanding genetic factors influencing reproductive outcomes is crucial for maternal and child health.

Purpose of the Study:

  • To investigate the association between maternal phosphoglucomutase (PGM) phenotype and fertility parameters.
  • To explore the relationship between PGM type, maternal age, and reproductive outcomes such as abortion and fetal growth.

Main Methods:

  • A study of 204 women who delivered a normal live-born child in Rome.
  • Analysis of phosphoglucomutase (PGM) phenotype in relation to age, previous spontaneous abortion, gestational duration, and fetal intrauterine growth rate.

Main Results:

  • A significant association was found between maternal age and PGM phenotype.
  • Women of PGM Type 1 showed a reduced reproductive rate and an increased incidence of abortion, particularly at older ages.
  • Gestational duration and fetal intrauterine growth rate were significantly associated with maternal PGM phenotype.

Conclusions:

  • Maternal phosphoglucomutase (PGM) phenotype appears to influence zygote development and survival.
  • The PGM phenotype, in conjunction with maternal age, plays a complex role in reproductive success and intrauterine development.
