Downslanted palpebral fissures, and Sparse hair

High match ECTODERMAL DYSPLASIA 13, HAIR/TOOTH TYPE; ECTD13

Some ectodermal dysplasias are here classified as congenital disorders characterized by abnormal development in 2 or more ectodermal structures (hair, nails, teeth, and sweat glands) without other systemic findings. Ectodermal dysplasia-13 of the hair/tooth type is characterized by severe oligodontia accompanied by anomalies of hair and skin (Issa et al., 2016).

High match SEVERE INTELLECTUAL DISABILITY-POOR LANGUAGE-STRABISMUS-GRIMACING FACE-LONG FINGERS SYNDROME

Severe intellectual disability-poor language-strabismus-grimacing face-long fingers syndrome is a rare, genetic, syndromic intellectual disability disorder characterized by global development delay with very limited or absent speech and language, severe intellectual disability, long slender fingers, ocular abnormalities (typically strabismus or hypermetropia), and facial dysmorphism that includes a grimacing facial expression, a tubular-shaped nose with a prominent, broad base and tip, and other variable features, such as broad forehead, hypertelorism, deep-set eyes, narrow palpebral fissures, short philtrum and/or broad mouth.

High match DEVELOPMENTAL DELAY DUE TO METHYLMALONATE SEMIALDEHYDE DEHYDROGENASE DEFICIENCY

Developmental delay due to methylmalonate semialdehyde dehydrogenase deficiency is a rare, genetic, inborn error of branched-chain amino acid metabolism disorder, with a highly variable clinical and biochemical phenotype, typically characterized by mild to severe global developmental delay, elevated methylmalonic acid and, occasionally, lactic acid plasma levels, and chronic methylmalonic aciduria, which may be accompanied by elevation of additional organic or amino acids in urine (e.g. beta-alanine, methionine, 3-hydroxypropionic, 3-aminoisobutyric and/or 3-hydroxyisobutyric acid). Microcephaly, mild craniofacial dysmorphism, axial hypotonia, liver failure, and central nervous system abnormalities on MRI have also been reported.

High match CARDIOFACIOCUTANEOUS SYNDROME 2; CFC2

Cardiofaciocutaneous (CFC) syndrome is a multiple congenital anomaly disorder characterized by a distinctive facial appearance, heart defects, and mental retardation (summary by Niihori et al., 2006). In a phenotypic comparison of BRAF (OMIM )-positive and KRAS-positive individuals with CFC, Niihori et al. (2006) observed that patients with KRAS mutations did not have the skin abnormalities, such as ichthyosis, hyperkeratosis, and hemangioma, that were present in patients with BRAF mutation.

High match COFFIN-SIRIS SYNDROME 7; CSS7

Coffin-Siris syndrome-7 is an autosomal dominant neurodevelopmental disorder characterized by global developmental delay with mild to moderate intellectual disability, speech impairment, behavioral abnormalities, poor overall growth, coarse facial features, and hypoplastic fifth toenails (summary by Vasileiou et al., 2018).For a general phenotypic description and a discussion of genetic heterogeneity of Coffin-Siris syndrome, see CSS1 (OMIM ).
