Transthyretin (TTR)-related familial amyloidotic cardiomyopathy is a hereditary TTR-related systemic amyloidosis (ATTR) with predominant cardiac involvement resulting from myocardial infiltration of abnormal amyloid protein.

Nephrogenic diabetes insipidus is caused by the inability of the renal collecting ducts to absorb water in response to antidiuretic hormone (ADH), also known as arginine vasopressin (AVP ). Approximately 90% of patients are males with the X-linked recessive form, type I (OMIM ), which is caused by mutation in the gene encoding the vasopressin V2 receptor (AVPR2 ). The remaining 10% of patients have the autosomal form, type II, caused by mutation in the AQP2 gene (Morello and Bichet, 2001).Neurogenic, or central, diabetes insipidus (CDI ) is caused by mutation in the gene encoding arginine vasopressin, located on 20p13.

Nephrogenic diabetes insipidus (NDI) is characterized by polyuria with polydipsia, recurrent bouts of fever, constipation, and acute hypernatremic dehydration after birth that may cause neurological sequelae. Polyuria may exceed 10 litres in children.

Nephropathic infantile cystinosis is the most common and severe form of cystinosis (see this term), a metabolic disease characterized by an accumulation of cystine inside the lysosomes that causes damage in different organs and tissues, particularly in the kidneys and eyes.

MOGS-CDG is a form of congenital disorders of N-linked glycosylation characterized by generalized hypotonia, craniofacial dysmorphism (prominent occiput, short palpebral fissures, long eyelashes, broad nose, high arched palate , retrognathia), hypoplastic genitalia, seizures, feeding difficulties, hypoventilation, severe hypogammaglobulinemia with generalized edema, and increased resistance to particular viral infections (particularly to enveloped viruses). The disease is caused by loss-of-function mutations in the gene MOGS (2p13.1).

Non-progressive cerebellar ataxia with intellectual deficit is a rare subtype of autosomal dominant cerebellar ataxia type 1 (ADCA type 1; see this term) characterized by the onset in infancy of cerebellar ataxia, neonatal hypotonia (in some), mild developmental delay and, in later life, intellectual disability. Less common features include dysarthria, dysmetria and dysmorphic facial features (long face, bulbous nose long philtrum, thick lower lip and pointed chin).

Neurohypophyseal diabetes insipidus is an autosomal dominant disorder of free water conservation characterized by childhood onset of polyuria and polydipsia. Affected individuals are apparently normal at birth, but characteristically develop symptoms of vasopression deficiency during childhood (summary by Wahlstrom et al., 2004).

Bartter syndrome refers to a group of disorders that are unified by autosomal recessive transmission of impaired salt reabsorption in the thick ascending loop of Henle with pronounced salt wasting, hypokalemic metabolic alkalosis, and hypercalciuria. Clinical disease results from defective renal reabsorption of sodium chloride in the thick ascending limb (TAL) of the Henle loop, where 30% of filtered salt is normally reabsorbed (Simon et al., 1997).Patients with antenatal forms of Bartter syndrome typically present with premature birth associated with polyhydramnios and low birth weight and may develop life-threatening dehydration in the neonatal period. Patients with classic Bartter syndrome (see BARTS3, {607364}) present later in life and may be sporadically asymptomatic or mildly symptomatic (summary by Simon et al., 1996 and Fremont and Chan, 2012).For a discussion of genetic heterogeneity of Bartter syndrome, see {607364}.

Infantile hypotonia with psychomotor retardation and characteristic facies (IHPRF) is a severe autosomal recessive neurologic disorder with onset at birth or in early infancy. Affected individuals show very poor, if any, normal cognitive development. Some patients are never learn to sit or walk independently (summary by Al-Sayed et al., 2013). Genetic Heterogeneity of Infantile Hypotonia with Psychomotor Retardation and Characteristic FaciesSee also IHPRF2 (OMIM ), caused by mutation in the UNC80 gene (OMIM ) on chromosome 2q34; and IHPRF3 (OMIM ), caused by mutation in the TBCK gene (OMIM ) on chromosome 4q24.
