Mutations in PROSC Disrupt Cellular Pyridoxal Phosphate Homeostasis and Cause Vitamin B6-Dependent Epilepsy [PDF]

open access: yes, 2016
Pyridoxal 5'-phosphate (PLP), the active form of vitamin B6, functions as a cofactor in humans for more than 140 enzymes, many of which are involved in neurotransmitter synthesis and degradation.

Alkaline phosphatases in the complex chronic kidney disease-mineral and bone disorders [PDF]

open access: yes, 2018
Alkaline phosphatases (APs) remove the phosphate (dephosphorylation) needed in multiple metabolic processes (from many molecules such as proteins, nucleotides, or pyrophosphate). Therefore, APs are important for bone mineralization but paradoxically they

Incremental yield of prenatal exome sequencing in fetuses with skeletal system abnormalities: A systematic review and meta‐analysis

open access: yesActa Obstetricia et Gynecologica Scandinavica, Volume 104, Issue 4, Page 604-614, April 2025.
Our study suggests that exome sequencing adds approximately 60% of the diagnostic yield in fetuses with skeletal abnormalities reported in previous literature. The dysplasia phenotypes had a higher incremental yield, whereas the dysostoses group according to this study had a relatively lower yield, especially in the isolated dysostoses group.

Perinatal Hypophosphatasia in a Premature Infant

open access: yesAmerican Journal of Perinatology Reports, 2020
A premature male infant was delivered at 32 weeks' gestation due to category-2 fetal tracing after preterm labor. The physical exam showed shortened and bowed long bones, with calvarium felt in small area of the head.

Proteoliposomes as matrix vesicles' biomimetics to study the initiation of skeletal mineralization [PDF]

open access: yes
During the process of endochondral bone formation, chondrocytes and osteoblasts mineralize their extracellular matrix by promoting the formation of hydroxyapatite (HA) seed crystals in the sheltered interior of membrane-limited matrix vesicles (MVs). Ion

Clinical, biochemical and genetic spectrum of low alkaline phosphatase levels in adults [PDF]

open access: yes, 2016
Background: Low serum levels of alkaline phosphatase (ALP) are a hallmark of hypophosphatasia. However, the clinical significance and the underlying genetics of low ALP in unselected populations are unclear.

‘Bone Health—Across a Woman's Lifespan’

open access: yesClinical Endocrinology, Volume 102, Issue 4, Page 389-402, April 2025.
ABSTRACT Despite a high burden of osteoporosis and minimal trauma fractures worldwide, there is still a treatment gap in timely diagnosis and optimal treatment. There is also a lack of international consensus and guidelines on the management of bone fragility in premenopausal women.

Bone-Targeted Alkaline Phosphatase Treatment of Mandibular Bone and Teeth in Lethal Hypophosphatasia via an scAAV8 Vector

open access: yesMolecular Therapy: Methods & Clinical Development, 2018
Hypophosphatasia is an inherited disease caused by mutations in the gene encoding tissue-nonspecific alkaline phosphatase (TNALP), the major symptom of which is hypomineralization of the bones and teeth. We had recently demonstrated that TNALP-deficient (

Unlocking the Mysteries of Rare Disease Drug Development: A Beginner's Guide for Clinical Pharmacologists

open access: yesClinical and Translational Science, Volume 18, Issue 4, April 2025.
ABSTRACT Clinical pharmacologists face unique challenges when developing drugs for rare diseases. These conditions are characterized by small patient populations, diverse disease progression patterns, and a limited understanding of underlying pathophysiology.

Prevalence of Individuals With Multiple Diagnosed Genetic Diseases in the Undiagnosed Diseases Network

open access: yesAmerican Journal of Medical Genetics Part A, Volume 197, Issue 2, February 2025.
ABSTRACT Report the prevalence of multiple genetic diseases in the Undiagnosed Diseases Network (UDN) cohort in the post‐exome‐sequencing era. UDN subjects underwent genome sequencing before inclusion in the cohort. Records of all UDN subjects until January 2024 were analyzed.
