Glycosylphosphatidylinositol biosynthesis defect 17(GPIBD17)

MedGen UID:
1648437
Concept ID:
C4747891
Disease or Syndrome
Synonyms: GLYCOSYLPHOSPHATIDYLINOSITOL BIOSYNTHESIS DEFECT 17; GPIBD17
 
Gene (location): PIGH (14q24.1)
 
Monarch Initiative: MONDO:0060724
OMIM®: 618010

Definition

Glycosylphosphatidylinositol biosynthesis defect-17 (GPIBD17) is an autosomal recessive disorder characterized by variable neurologic deficits that become apparent in infancy or early childhood. Patients may present with early-onset febrile or afebrile seizures that tend to be mild or controllable. Other features may include learning disabilities, autism, behavioral abnormalities, hypotonia, and motor deficits. The phenotype is relatively mild compared to that of other GPIBDs (summary by Nguyen et al., 2018). For a discussion of genetic heterogeneity of GPI biosynthesis defects, see GPIBD1 (610293). [from OMIM]

Clinical features

From HPO
Clinodactyly of the 5th finger
MedGen UID:
340456
Concept ID:
C1850049
Congenital Abnormality
Clinodactyly refers to a bending or curvature of the fifth finger in the radial direction (i.e., towards the 4th finger).
Clinodactyly of the 5th toe
MedGen UID:
871256
Concept ID:
C4025741
Anatomical Abnormality
Bending or curvature of a fifth toe in the tibial direction (i.e., towards the big toe).
Growth delay
MedGen UID:
99124
Concept ID:
C0456070
Pathologic Function
A deficiency or slowing down of growth pre- and postnatally.
Abnormal ear morphology
MedGen UID:
1640667
Concept ID:
C4703491
Anatomical Abnormality
Any structural anomaly of the ear.
Aggressive behavior
MedGen UID:
1375
Concept ID:
C0001807
Individual Behavior
Aggressive behavior can denote verbal aggression, physical aggression against objects, physical aggression against people, and may also include aggression towards oneself.
Seizure
MedGen UID:
20693
Concept ID:
C0036572
Sign or Symptom
A seizure is an intermittent abnormality of nervous system physiology characterised by a transient occurrence of signs and/or symptoms due to abnormal excessive or synchronous neuronal activity in the brain.
Dysplastic corpus callosum
MedGen UID:
98128
Concept ID:
C0431369
Congenital Abnormality
Dysplasia and dysgenesis of the corpus callosum are nonspecific descriptions that imply defective development of the corpus callosum. The term dysplasia is applied when the morphology of the corpus callosum is altered as a congenital trait. For instance, the corpus callosum may be hump-shaped, kinked, or a striped corpus callosum that lacks an anatomically distinct genu and splenium.
Global developmental delay
MedGen UID:
107838
Concept ID:
C0557874
Finding
A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.
Poor speech
MedGen UID:
341172
Concept ID:
C1848207
Finding
Overfriendliness
MedGen UID:
867995
Concept ID:
C4022386
Mental or Behavioral Dysfunction
A form of hypersociability that presents as mostly inappropriate people-orientation and friendliness towards others on an inadequate level which might go as far as being dangerous considering for example young children following strangers without restriction.
Specific learning disability
MedGen UID:
871302
Concept ID:
C4025790
Mental or Behavioral Dysfunction
Impairment of certain skills such as reading or writing, coordination, self-control, or attention that interfere with the ability to learn. The impairment is not related to a global deficiency of intelligence.
Generalized hypotonia
MedGen UID:
346841
Concept ID:
C1858120
Finding
Generalized muscular hypotonia (abnormally low muscle tone).
Primary microcephaly
MedGen UID:
383046
Concept ID:
C2677180
Finding
Head circumference below 2 standard deviations below the mean for age and gender at birth.
Hypertriglyceridemia
MedGen UID:
167238
Concept ID:
C0813230
Finding
An abnormal increase in the level of triglycerides in the blood.
High palate
MedGen UID:
66814
Concept ID:
C0240635
Congenital Abnormality
Height of the palate more than 2 SD above the mean (objective) or palatal height at the level of the first permanent molar more than twice the height of the teeth (subjective).
