A Homozygous Nonsense Thyroid Peroxidase Mutation (R540X) Consistently Causes Congenital Hypothyroidism in Two Siblings Born to a Consanguineous Family
OBJECTIVE Congenital hypothyroidism (CH) is the most common neonatal endocrine disorder, and mutations in the thyroid peroxidase (TPO) gene have been reported to cause the disease. Our aim in this study was to determine the genetic basis of CH in two affected children coming from a consanguineous family. METHODS First, we investigated the potential genetic linkage of the family to any known C...
متن کاملPendred syndrome in a large consanguineous Brazilian family caused by a homozygous mutation in the SLC26A4 gene.
Pendred Syndrome (PS) is an autossomal recessive disorder characterized by sensorineural deafness, goiter and iodide organification defect. The hearing loss is associated with inner ear abnormalities, ranging from an isolated enlarged vestibular aqueduct (EVA) to a typical coclear dysplasia. Mutations in the gene that encodes pendrin (SLC26A4), a chloride/iodide transporter, have been shown to ...
متن کاملA homozygous mutation in a consanguineous family consolidates the role of ALDH1A3 in autosomal recessive microphthalmia.
Anomalies of eye development can lead to the rare eye malformations microphthalmia and anophthalmia (small or absent ocular globes), which are genetically very heterogeneous. Several genes have been associated with microphthalmia and anophthalmia, and exome sequencing has contributed to the identification of new genes. Very recently, homozygous variations within ALDH1A3 have been associated wit...
متن کاملTetra-Amelia Syndrome
A newborn was noticed lying unattended in the hospital campus. It had complete absence of all four limbs, deformed ears, facial cleft, proptosis, hydrocephalus, corneal opacity, absent nipples, anterior abdominal wall defect with exstrophy bladder, absent external genitalia, and sacral spina bifida (Fig.1 A & B). The child died after few hours due to aspiration pneumonitis. These features are p...
متن کاملA Novel Missense Mutation in the ALDH13 Gene Causes Anophthalmia in Two Unrelated Iranian Consanguineous Families
Anophthalmia or microphthalmia (A/M) is a rare group of congenital/developmental ocular malformations, characterized by absent or small eye within the orbit affecting one or both eyes. It has complex etiology with chromosomal, monogenic with high heterogeneity, and environmental causes. We performed genome SNP-array analysis followed by autozygosity mapping and sequencing in the members o...
