Growth delay, and Atopic dermatitis

Singleton-Merten syndrome-2 is characterized by variable expression of glaucoma, aortic calcification, and skeletal abnormalities, without dental anomalies (summary by Jang et al., 2015).For a general phenotypic description and discussion of genetic heterogeneity of Singleton-Merten syndrome, see SGMRT1 (OMIM ).

Immunodeficiency-55 is an autosomal recessive primary immunodeficiency characterized by intrauterine growth retardation, natural killer (NK) cell deficiency, and chronic neutropenia. Most patients also have postnatal growth retardation. Other clinical manifestations include mild facial dysmorphism, dry or eczematous skin, and recurrent infections with both viruses and bacteria. The disorder appears to result from a defect in DNA replication causing blockade of immune cell differentiation in the bone marrow, particularly affecting NK cells (summary by Cottineau et al., 2017).

Infantile-onset multisystem autoimmune disease-1 is characterized by early childhood onset of a spectrum of autoimmune disorders affecting multiple organs. Common manifestations include insulin-dependent diabetes mellitus and autoimmune enteropathy, or celiac disease, and autoimmune hematologic disorders. Other features include short stature and nonspecific dermatitis. More variable features include hypothyroidism, autoimmune arthritis, and delayed puberty. Some patients may show recurrent infections. The disorder results from an inborn error of cytokine signaling (summary by Flanagan et al., 2014 and Milner et al., 2015). Genetic Heterogeneity of Infantile-Onset Multisystem Autoimmune DiseaseSee also ADMIO2 (OMIM ), caused by mutation in the ZAP70 gene (OMIM ) on chromosome 2q12.

Aicardi-Goutieres syndrome-7 is an autosomal dominant inflammatory disorder characterized by severe neurologic impairment. Most patients present in infancy with delayed psychomotor development, axial hypotonia, spasticity, and brain imaging changes, including basal ganglia calcification, cerebral atrophy, and deep white matter abnormalities. Laboratory evaluation shows increased alpha-interferon (IFNA1 ) activity with upregulation of interferon signaling and interferon-stimulated gene expression. Some patients may have normal early development followed by episodic neurologic regression (summary by Rice et al., 2014).For a phenotypic description and a discussion of genetic heterogeneity of Aicardi-Goutieres syndrome, see AGS1 (OMIM ).

PGM3-CDG is a rare congenital disorder of glycosylation caused by mutations in the PGM3 gene and characterized by neonatal to childhood onset of recurrent bacterial and viral infections, inflammatory skin diseases, atopic dermatitis and atopic diatheses, and marked serum IgE elevation. Early neurologic impairment is evident including developmental delay, intellectual disability, ataxia, dysarthria, sensorineural hearing loss, myoclonus and seizures.

EVEN-PLUS syndrome is characterized by prenatal-onset short stature, vertebral and epiphyseal changes, microtia, midface hypoplasia with flat nose and triangular nares, cardiac malformations, and other findings including anal atresia, hypodontia, and aplasia cutis. The features overlap those reported in patients with CODAS syndrome ({600373}; Royer-Bertrand et al., 2015).

Noonan-like syndrome with loose anagen hair (NS/LAH) is a Noonan-related syndrome, characterized by facial anomalies suggestive of Noonan syndrome (see this term); a distinctive hair anomaly described as loose anagen hair syndrome (see this term); frequent congenital heart defects; distinctive skin features with darkly pigmented skin, keratosis pilaris, eczema or occasional neonatal ichtyosis (see this term); and short stature, often associated with a GH deficiency and psychomotor delays.
