Global developmental delay, and Stage 5 chronic kidney disease

Pierson syndrome is characterised by the association of congenital nephrotic syndrome and ocular anomalies with microcoria.

PIERSON SYNDROME Is also known as microcoria-congenital nephrotic syndrome|microcoria-congenital nephrosis syndrome

Neonatal sclerosing cholangitis is a rare autosomal recessive form of severe liver disease with onset in infancy. Affected infants have jaundice, cholestasis, acholic stools, and progressive liver dysfunction resulting in fibrosis and cirrhosis; most require liver transplantation in the first few decades of life. Cholangiography shows patent biliary ducts, but there are bile duct irregularities (summary by Girard et al., 2016; Grammatikopoulos et al., 2016).

Galloway-Mowat syndrome is a renal-neurologic disease characterized by early-onset nephrotic syndrome associated with microcephaly, gyral abnormalities, and delayed psychomotor development. Most patients have dysmorphic facial features, often including hypertelorism and ear abnormalities. Other features, such as arachnodactyly and visual or hearing impairment, are more variable. Most patients die in the first years of life (summary by Braun et al., 2017).For a general phenotypic description and a discussion of genetic heterogeneity of GAMOS, see GAMOS1 (OMIM ).

Joubert syndrome is an autosomal recessive disorder presenting with psychomotor delay, hypotonia, ataxia, oculomotor apraxia, and neonatal breathing abnormalities. Neuroradiologically, Joubert syndrome is characterized by peculiar malformation of the midbrain-hindbrain junction known as the 'molar tooth sign' (MTS) consisting of cerebellar vermis hypoplasia or aplasia, thick and maloriented superior cerebellar peduncles, and abnormally deep interpeduncular fossa (Romano et al., 2006).For a phenotypic description and a discussion of genetic heterogeneity of Joubert syndrome, see {213300}.

Galloway-Mowat syndrome is a renal-neurologic disease characterized by early-onset nephrotic syndrome associated with microcephaly, gyral abnormalities, and delayed psychomotor development. Most patients have dysmorphic facial features, often including hypertelorism, ear abnormalities, and micrognathia. Other features, such as arachnodactyly and visual impairment, are more variable. Most patients die in the first years of life (summary by Braun et al., 2017).For a general phenotypic description and a discussion of genetic heterogeneity of GAMOS, see GAMOS1 (OMIM ).

Senior-Loken syndrome-9 is an autosomal recessive disorder characterized by early-onset nephronophthisis and pigmentary retinopathy. Additional more variable features can include liver defects, skeletal anomalies, and obesity (summary by Bizet et al., 2015).For a phenotypic description and a discussion of genetic heterogeneity of Senior-Loken syndrome, see {266900}.

BBS16 is an autosomal recessive ciliopathy characterized by retinal degeneration, obesity, renal disease, and cognitive impairment. Although polydactyly is considered a primary feature of BBS overall, it has not been reported in any BBS16 patient (Billingsley et al., 2012).For a general phenotypic description and a discussion of genetic heterogeneity of Bardet-Biedl syndrome, see BBS1 (OMIM ).
