- Disability
How is intellectual disability diagnosed? Intellectual disability may be suspected for many different reasons. [webmd.com]
Genetic investigations in intellectual disability. For many cases of intellectual disability (ID) of unknown origin, a genetic basis is assumed. [epilepsygenetics.net]
Kruse et al., (1988) described nine patients (six females) with hyperphosphatasia and intellectual disability. [fdna.health]
[…] intellectual disability that is often moderate to severe. [ncbi.nlm.nih.gov]
The expressivity of the clinical features in HPMRS varies from severe syndromic forms with multiple organ malformations to mild nonsyndromic intellectual disability. [spiral.imperial.ac.uk]

Gastrointestinal
- Abdominal Distension
History was remarkable for suspected milk and soy protein allergy, gastroesophageal reflux, constipation, and abdominal distension that was present since birth. He was losing weight despite oral intake of over 100 kcal/kg per day. [readbyqxmd.com]
Soon after birth, he presented with abdominal distension and vomiting. A rectal biopsy showed short-segment Hirschsprung disease which required colostomy and anal dilatations. Bilateral supernumerary nipples were noted. [dev.docslide.net]

Brachytelephalangy was present with hypoplastic nails, especial- ly on thumbs and little fingers. She developed a mild scoliosis. Alkaline phosphatase activity was increased to between 1,937 and 2,069U/L (NR< 410U/L). A karyotype was normal. [dev.docslide.net]

The distinct pattern of facial anomalies present in all patients consisted of wide-set eyes, often with a large appearance, a short nose with a broad nasal bridge and tip, and a tented upper lip ( Figures 2 and 4 ). [nature.com]
Facial dysmorphic features including hypertelorismwith elongated palpebral fissures, broad nasal bridge, and tented upper lip with downturnedcorners of themouthare common toall cases (Table I). [dev.docslide.net]
- Thin Lips
Those facial findings of greatest diagnostic value were the combination of the characteristic eyebrows, long philtrum, thin lips and crescent‐shaped mouth. [doi.org]
Neurologic
- Convulsions
Seizures are usually the generalized tonic-clonic type, which involve muscle rigidity, convulsions, and loss of consciousness.Individuals with Mabry syndrome have distinctive facial features that include wide-set eyes (hypertelorism), long openings of [ncbi.nlm.nih.gov]
A single male with intellectual disability and convulsions was reported by Gomes and Hunter (1970). At 28 months, he was noted to have bilateral cataracts, and a 3-cm liver was noted when he was 4 years of age. [fdna.health]
- Generalized Tonic-Clonic Seizure
Frequent generalized tonic-clonic seizures commenced at age 4 years. Treatment with valproic acid and rufinamide resulted in partial control of seizures. Cluster seizures were treated with clonazepam. [dev.docslide.net]
Workup
Prior workup including laboratory studies, abdominal X-ray, upper gastrointestinal series with fluoroscopy, barium enema, and abdominal ultrasound were all within normal limits. [readbyqxmd.com]
Clinical Testing and Workup If indicated, further examinations and specialized imaging techniques are recommended to establish the extent of the disorder. [rarediseases.org]
We hope that a functional workup of these mutations with respect to their protein impairment of PIGV will enable a better prediction of the phenotypic outcome of the patients based on the genotype information. References 1. [nature.com]

In addition, affected infants and children may have hypotonia, abnormally loose joints, delayed bone age (2 to 3 years behind the chronological age), and mild to severe intellectual disability. [rarediseases.org]
