I-cell disease (Mucolipidosis II) is one of the lysosomal storage diseases which presents in the neonatal period, and within six months will phenotypically resemble the severe forms of the group of disorders called the "mucopolysaccharidoses" but without mucopolysacchariduria. In Mucolipidosis II, fibrocytes exhibit "abnormal lysosomes".

The exact prevalence is unknown due to scarce data. Previous studies from different countries estimate a variable prevalence ranging from 1 in 625500 to 1 in 123 500 live births. Mucolipidosis II (I-cell disease) and mucolipidosis IIIA (classical pseudo-hurler polydystrophy) are caused by mutations in the GlcNAc-phosphotransferase alpha / beta -subunits precursor gene. Am J Hum Genet. 2006 Mar;78(3):451-63. 2021-04-06 · I-cell disease is a rare genetic disorder also known as mucolipidosis II (ML II). It causes symptoms such as skeletal abnormalities, rough facial features, mental disabilities, death usually occurs in childhood. One in a million.
Part of the lysosomal storage disease family and results from a defective phosphotransferase ( an enzyme of the Golgi apparatus). I-cell disease is also known as: GNPTA, Inclusion Cell Disease, Leroy Disease, ML Disorder, Type II, ML II, Mucolipidosis II, or N-Acetylglucosamine-1-Phosphotransferase Deficiency.

Mucolipidosis II (ML II), also known as I cell disease, is a rare and progressive metabolic disorder that involves our body’s ability to break down certain fats ( mucolipids).
Developmental delay and growth failure are the first signs of I Cell Disease, and present in the first year of life. In contrast, I-cell fibroblasts, within the limits of the assay, lack this enzyme activity. AB - Cultured fibroblasts from three unrelated patients with I-cell disease (mucolipidosis II) have a 3 to 4 fold increase in total sialic acid when compared to control fibroblasts. 2021-02-19 · I-cell disease (mucolipidosis type II) Pseudo-Hurler disease (mucolipidosis type III) Sialolipidosis (mucolipidosis type IV) I-cell disease. Definition: an autosomal recessive disease caused by a defect in N-acetylglucosaminyl-1-phosphotransferase activity; Pathophysiology

Affected newborns are small for gestational age and may have hyperplastic gums. Coarsening of facial features and limitation of joint movements occur within the first months. I-cell disease is characterized by severe psychomotor retardation that rapidly progresses leading to death between 5 and 8 years of age. Although there are similar signs and symptoms, the earlier onset of symptoms and the lack of mucopolysacchariduria distinguish I-cell disease from Hurler syndrome.

See also. Mucolipidosis; References ^ Tiede S, Storch S, Lübke T, et al (2005). I‐cell disease has been reported by many authors but the electron microscopic findings have been reported only rarely. The patient under study was a female infant with a normal delivery after 38 weeks’normal intrauterine life. She showed the physical findings characteristic of I‐cell‐disease, and the diagnosis was made by the analyses of lysosomal enzymes.
What is I-cell disease testing? I-cell disease is a rare genetic disorder also known as mucolipidosis II (ML II). It causes symptoms such as skeletal abnormalities, rough facial features, mental disabilities, death usually occurs in childhood. Biochemical testing for I-cell disease involves the collection and analysis of plasma and urine.
