HYPERCOAGULABILITY SYNDROME DUE TO GLYCOSYLPHOSPHATIDYLINOSITOL DEFICIENCY

Alternate names

HYPERCOAGULABILITY SYNDROME DUE TO GLYCOSYLPHOSPHATIDYLINOSITOL DEFICIENCY Is also known as pigm-cdg, congenital disorder of glycosylation due to pigm deficiency, glycosylphosphatidylinositol biosynthesis defect 1, gpibd1

Description

The combination of a propensity for venous thrombosis and seizures has been reported in two unrelated kindreds. Transmission is autosomal recessive. It results from a point mutation of PIGM, which reduces transcription of PIGM and blocks mannosylation of glycosylphosphatidylinositol (GPI), leading to partial but severe deficiency of GPI.

Most common symptoms of HYPERCOAGULABILITY SYNDROME DUE TO GLYCOSYLPHOSPHATIDYLINOSITOL DEFICIENCY

  • Intellectual disability
  • Seizures
  • Abnormal facial shape
  • Hypertension
  • Hepatomegaly

HYPERPHOSPHATASIA-INTELLECTUAL DISABILITY SYNDROME

Alternate names

HYPERPHOSPHATASIA-INTELLECTUAL DISABILITY SYNDROME Is also known as mabry syndrome, glycosylphosphatidylinositol biosynthesis defect 2, gpibd2

Description

Hyperphosphatasia with mental retardation syndrome-1 is an autosomal recessive disorder characterized by mental retardation, various neurologic abnormalities such as seizures and hypotonia, and hyperphosphatasia. Other features include facial dysmorphism and variable degrees of brachytelephalangy (summary by Krawitz et al., 2010). The disorder is caused by a defect in glycosylphosphatidylinositol biosynthesis; see GPIBD1 (OMIM ). Genetic Heterogeneity of Hyperphosphatasia with Mental Retardation SyndromeSee also HPMRS2 (OMIM ), caused by mutation in the PIGO gene (OMIM ) on chromosome 9p13; HPMRS3 (OMIM ), caused by mutation in the PGAP2 gene (OMIM ) on chromosome 11p15; HPMRS4 (OMIM ), caused by mutation in the PGAP3 gene (OMIM ) on chromosome 17q12; HPMRS5 (OMIM ), caused by mutation in the PIGW gene (OMIM ) on chromosome 17q12; and HPMRS6 (OMIM ), caused by mutation in the PIGY gene (OMIM ) on chromosome 4q22.Knaus et al. (2018) provided a review of the main clinical features of the different types of HPMRS, noting that some patients have a distinct pattern of facial anomalies that can be detected by computer-assisted comparison, particularly those with mutations in the PIGV and PGAP3 genes. Individuals with HPMRS have variable increased in alkaline phosphatase (AP) as well as variable decreases in GPI-linked proteins that can be detected by flow cytometry. However, there was no clear correlation between AP levels or GPI-linked protein abnormalities and degree of neurologic involvement, mutation class, or gene involved. Knaus et al. (2018) concluded that a distinction between HPMRS and MCAHS (see, e.g., {614080}), which is also caused by mutation in genes involved in GPI biosynthesis, may be artificial and even inaccurate, and that all these disorders should be considered and classified under the more encompassing term of 'GPI biosynthesis defects' (GPIBD).

Most common symptoms of HYPERPHOSPHATASIA-INTELLECTUAL DISABILITY SYNDROME

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Generalized hypotonia
  • Hearing impairment

GLYCOSYLPHOSPHATIDYLINOSITOL BIOSYNTHESIS DEFECT 11; GPIBD11

Alternate names

GLYCOSYLPHOSPHATIDYLINOSITOL BIOSYNTHESIS DEFECT 11; GPIBD11 Is also known as hyperphosphatasia with mental retardation syndrome 5, hpmrs5

Description

GPIBD11 is an autosomal recessive disorder characterized by neonatal hypotonia, lack of psychomotor development, and variable seizures. Some patients may have dysmorphic features or increased serum alkaline phosphatase. The disorder is caused by a defect in glycosylphosphatidylinositol (GPI) biosynthesis (summary by Hogrebe et al., 2016).For a discussion of genetic heterogeneity of GPI biosynthesis defects, see GPIBD1 (OMIM ).

Most common symptoms of GLYCOSYLPHOSPHATIDYLINOSITOL BIOSYNTHESIS DEFECT 11; GPIBD11

  • Intellectual disability
  • Seizures
  • Global developmental delay
  • Generalized hypotonia
  • Abnormal facial shape
