BioHypophos – Biomarker for Hypophosphatasia Disease
Hypophosphatasia (HPP) is a rare genetic disorder characterized the abnormal devel-opment of bones and teeth. These abnormalities occur due to defective mineralization, the process by which bones and teeth take up…

BioAlport – Biomarker for Alport Disease
Alport Syndrome is an inherited disease that primarily affects the glomeruli, the tiny tufts of capillaries in the kidneys that filter wastes from the blood. The disease was first described by an English doctor named A.…

A Novel PORCN Mutation in a Severe Case of Focal Dermal Hypoplasia
Focal dermal hypoplasia is an unusual genetic disease that affects ectodermal and mesodermal derivatives. This is the case of an eight year old female from Colombia with multiple congenital malformations.

A Recessive Form of Extreme Macrocephaly
PTEN hamartoma tumour syndrome (PHTS) is caused by heterozygous variants in PTEN and is characterised by tumour predisposition, macrocephaly, and cognition impairment. Bi-allelic loss of PTEN activity has not been…

Mendelian Disease Gene Identification and Diagnostics Using Targeted Next Generation Sequencing
During the last few months we have observed for the first time since the introduction of the first massive parallel sequencers in 2007, that the cost of sequencing a human genome has not changed significantly.

Molecular, Biochemical, and Structural Analysis of a Novel Mutation in Patients with Methylmalonyl-CoA Mutase Deficiency
Methylmalonic aciduria (MMA) is an inborn error of metabolism resulting from genetic defects in methylmalonyl-CoA mutase (MCM). We found one homozygous nucleotide change in intron 12 of the MUT gene (c.2125-3 C > G).

Proof-of-Principle Rapid Noninvasive Prenatal Diagnosis of Autosomal Recessive Founder Mutations
Proof-of-principle rapid noninvasive prenatal diagnosis of autosomal recessive founder mutations. Ten parental alleles in eight unrelated fetuses were diagnosed successfully based on the noninvasive method developed in…

Recurrent Null Mutation in SPG20
Troyer syndrome is an autosomal recessive form of complex hereditary spastic paraplegia. To date, the disorder has only been described in the Amish and in kindred from Oman. In Amish, all affected individuals have a…

TALPID3 Controls Centrosome
Joubert syndrome (JBTS) is a severe recessive neurodevelopmental ciliopathy which can affect several organ systems. Mutations in known JBTS genes account for approximately half of the cases. By homozygosity mapping and…

Diagnosis of Morquio Syndrome in Dried Blood Spots Based on a New MRM-MS Assay
Mucopolysaccharidosis IVA (MPS IVA; Morquio A disease) is an autosomal recessive disease caused and characterized by a decreased activity of N-acetylgalactosamine-6- sulfate sulfatase (GALNS), resulting in accumulation…
