00025920 - PubMed: Krawitz 2010, PubMed: Horn 2010 3 siblings of unrelated parents with hyperphosphatasia and severe mental retardation syndrome. - no Germany white - - - - HPMRS1;GPIBD2 Oldest patien twas a 4-year-old girl, her brothers were dizygotic twin brothers of patient 1 and were 18 months old at time of first evaluation. Facial anomalies comprised hypertelorism, large appearing eyes, a short nose with a broad nasal bridge and tip, thin upper lip with down-turned corners of the mouth. Clinically and radiologically, shortness of several distal phalanges could be demonstrated which mainly affected digits II and V. All patients had a severe global developmental delay without any speech development. At two years, patient 2 developed seizures. Older sister had congenital megacolon. Twin brothers presented sensorineural deafness. PIGV PIGV 1 3 Philippe Campeau

F ? - - - - - - HPMRS1;GPIBD2 The patients presented developmental retardation, facial and skeletal anomalies, and hyperphosphatasia. Facial features included hyperthelorism, wide palpebral fissures, broad nasal bridge, downturned corners of mouth. The prsented nail hypoplasia. PIGV PIGV 2 2 Philippe Campeau
00025922 - PubMed: Krawitz 2010, PubMed: Marcelis Two sisters with hyperphospatasia mental retardation 1. F yes Morocco African - - - - HPMRS1;GPIBD2 These siblings share severe mental retardation, epilepsy, anterior displaced anus, and hypoplastic nails. Fetal pads were noted on all fingers and toes. The nail hypoplasia was associated with hypoplasia of the distal phalanx of the fifth finger in the older sibling. Elder sister died suddenly at age 10 years. PIGV PIGV 1 2 Philippe Campeau

F no Germany white - - - - HPMRS1;GPIBD2 Her psychomotor development was considerably delayed. Epilepsy started as early as in her first year of life which responded well to treatment with valproic acid. Serum alkaline phosphatase was significantly and constantly elevated. Dysmorphic facial features include widely spaced eyes with an upward slant of palpebral fissures, a broad nasal bridge and tip, and a tented upper lip. Her hands and feet show bilateral brachytelephalangy including small nails. Radiographs of her left hand and left foot disclosed abnormally short distal phalanges of fingers and toes, respectively.

00025926 - PubMed: Thompson 2012 Siblings with hyperphosphatasia with neurologic deficit. - no United Kingdom (Great Britain) white - - - - HPMRS1;GPIBD2 Elder sister was hypotonic at birth and had a round face, downturned mouth, and thickened helices. She developed tonic-clonic seizures at age 8 weeks. Renal ultrasound study showed unilateral hydronephrosis. She had an anteriorly placed anus and constipation, but a rectal biopsy showed normal innervation. Development was delayed and at the age 4 years. Long palpebral fissures, a prominent nasal bridge, simple cupped ears with thickened helices, and a tented upper lip with downturned corners of the mouth were observed. Brachytelephalangy was present with hypoplastic nails, especially on thumbs and little fingers. She developed a mild scoliosis. Her brother developed seizures after birth. He had Hirschsprung disease. He had simple cupped ears with thickened helices, a tented upper lip with downturned corners of the mouth, a high palate with bifid uvula, convergent squint, and glue ear. Development was profoundly delayed at age 5 years. Hypoplastic nails and diminutive terminal phalanges of all digits of both hands and feet suggested brachytelephalangy. He had problems swallowing secretions, and had multiple upper respiratory tract infections and was oxygen dependent. He died at 7 years of age. PIGV PIGV 2 1 Philippe Campeau
00025927 - PubMed: Thompson 2012 Index case with hyperphosphatasia with mental retardation. F yes Netherlands white - - - - HPMRS1;GPIBD2 At birth, features included a tented upper lip. Hands and feet were affected with hypoplasia of the terminal phalanges and missing nails on the second and fifth digits. At 2 years, Moderate to severe intellectual disability, hypotonia and growth delay were noted. Seizures developed after the age of 5 years. PIGV PIGV 2 1 Philippe Campeau
00025928 - PubMed: Thompson 2012 Index case with hyperphosphatasia with mental retardation 1. F no United States white - - - - HPMRS1;GPIBD2 Developmental delay was noted by the age of 16 months. Frequent generalized tonic-clonic seizures commenced at age 4 years. She had delayed psychomotor development and hypotonia, hypertelorism, a broad nasal bridge and tented upper lip. Her hands and feet were normal with no evidence of clinodactyly or brachytelephalangy. PIGV PIGV 1 1 Philippe Campeau
