  • Maternity center

    A free-standing institution one not directly attached to a hospital where women come to give birth, often attended by certified nurse-midwives; also called alternative birthing centers or simply birthing centers.

  • Maternal phenylketonuria

    Phenylketonuria (PKU) is an autosomal recessive inborn error of metabolism in which a person cannot metabolize phenylalanine (Phe) into tyrosine and its constituent components. As a result, Phe accumulates in the blood, causing widespread brain damage, consequent severe mental retardation, and other organic problems. Before birth, nutrients are metabolized by the mother and transmitted through…

  • Myotonia congenita

    Myotonia congenita is a hereditary muscle disease that belongs to a group of myotonic disorders seen in children. Myotonia congenita comes in two forms; autosomal dominant form (DMC), also known as Thomsen’s disease, and autosomal recessive form, or recessive generalized myotonia (RGM). The autosomal dominant myotonia congenita is slightly less severe, although both forms are…
