Medium match SKIN CREASES, CONGENITAL SYMMETRIC CIRCUMFERENTIAL, 2; CSCSC2

Congenital symmetric circumferential skin creases is characterized by the folding of excess skin, which leads to ringed creases, primarily of the limbs. Affected individuals also exhibit intellectual disability, cleft palate, and dysmorphic features (summary by Isrie et al., 2015).For a discussion of genetic heterogeneity of congenital symmetric circumferential skin creases, see CSCSC1 (OMIM ).

Medium match MEHMO SYNDROME

MEHMO syndrome is characterised by severe intellectual deficit, epilepsy, microcephaly, hypogenitalism, and obesity. Growth delay and diabetes are also present. To date, it has been described in seven boys, all of whom died within the first two years of life. The causative gene has been localised to the 21.1-22.13p region of the X chromosome and the syndrome appears to result from mitochondrial dysfunction.

Medium match SIMPSON-GOLABI-BEHMEL SYNDROME, TYPE 2; SGBS2

An extremely rare and severe early-lethal form of Simpson-Golabi-Behmel syndrome. The disease is an overgrowth-multiple anomalies syndrome with characteristics of hydrops fetalis, macrocephaly, facial dysmorphism, short neck, redundant skin, skeletal defects (involving upper and lower limbs), hypoplastic nails, gastrointestinal and genitourinary anomalies, hypotonia and neurologic impairment. Severe intellectual disability, obesity and infections (pneumonia, sepsis) have been reported.

Medium match HYPERPHOSPHATASIA-INTELLECTUAL DISABILITY SYNDROME

Hyperphosphatasia with mental retardation syndrome-1 is an autosomal recessive disorder characterized by mental retardation, various neurologic abnormalities such as seizures and hypotonia, and hyperphosphatasia. Other features include facial dysmorphism and variable degrees of brachytelephalangy (summary by Krawitz et al., 2010). The disorder is caused by a defect in glycosylphosphatidylinositol biosynthesis; see GPIBD1 (OMIM ). Genetic Heterogeneity of Hyperphosphatasia with Mental Retardation SyndromeSee also HPMRS2 (OMIM ), caused by mutation in the PIGO gene (OMIM ) on chromosome 9p13; HPMRS3 (OMIM ), caused by mutation in the PGAP2 gene (OMIM ) on chromosome 11p15; HPMRS4 (OMIM ), caused by mutation in the PGAP3 gene (OMIM ) on chromosome 17q12; HPMRS5 (OMIM ), caused by mutation in the PIGW gene (OMIM ) on chromosome 17q12; and HPMRS6 (OMIM ), caused by mutation in the PIGY gene (OMIM ) on chromosome 4q22.Knaus et al. (2018) provided a review of the main clinical features of the different types of HPMRS, noting that some patients have a distinct pattern of facial anomalies that can be detected by computer-assisted comparison, particularly those with mutations in the PIGV and PGAP3 genes. Individuals with HPMRS have variable increased in alkaline phosphatase (AP) as well as variable decreases in GPI-linked proteins that can be detected by flow cytometry. However, there was no clear correlation between AP levels or GPI-linked protein abnormalities and degree of neurologic involvement, mutation class, or gene involved. Knaus et al. (2018) concluded that a distinction between HPMRS and MCAHS (see, e.g., {614080}), which is also caused by mutation in genes involved in GPI biosynthesis, may be artificial and even inaccurate, and that all these disorders should be considered and classified under the more encompassing term of 'GPI biosynthesis defects' (GPIBD).

Coffin-Siris syndrome-6 is characterized by short stature, sparse hair, mild to severe intellectual disability, coarse facial features, and variable behavioral anomalies. Some patients have fifth digit clinodactyly with small nails. Other congenital anomalies and seizures may be present. This description is based on reports of 7 unrelated patients (Shang et al., 2015; Van Paemel et al., 2017; Bramswig et al., 2017).For a general phenotypic description and a discussion of genetic heterogeneity of Coffin-Siris syndrome, see CSS1 (OMIM ).
