High match BAMFORTH-LAZARUS SYNDROME

Bamforth-Lazarus syndrome is a very rare syndrome of congenital hypothyroidism characterized by thyroid dysgenesis (in most cases athyreosis), cleft palate and spiky hair, with or without choanal atresia, and bifid epiglottis. Facial dysmorphism and porencephaly have been reported in isolated cases.

High match BARTTER SYNDROME, TYPE 4B, NEONATAL, WITH SENSORINEURAL DEAFNESS; BARTS4B

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 (or neonatal) forms of Bartter syndrome (e.g., BARTS1, {601678}) 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 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}.

High match NEPHROGENIC DIABETES INSIPIDUS

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.

Spastic paraplegia, intellectual disability, nystagmus, and obesity (SINO) is an autosomal dominant neurologic disorder characterized by rapid growth in infancy, global developmental delay, spastic paraplegia, variable ophthalmologic defects, and dysmorphic facial features (summary by Josifova et al., 2016).

High match MICROCEPHALY 17, PRIMARY, AUTOSOMAL RECESSIVE; MCPH17

Autosomal recessive primary microcephaly-17 (MCPH17) is a severe neurologic disorder characterized by very small head circumference that is apparent at birth and worsens over time (up to -12 SD). Affected individuals have delayed psychomotor development, intellectual disability, spasticity, axial hypotonia, and dysmorphic features. Brain imaging shows a simplified gyral pattern; more severe cases have lissencephaly with hypoplasia of the brainstem and cerebellum (summary by Harding et al., 2016).For a phenotypic description and a discussion of genetic heterogeneity of primary microcephaly, see MCPH1 (OMIM ).
