Medium match STROMME SYNDROME; STROMS

Stromme syndrome is an autosomal recessive congenital disorder affecting multiple systems with features of a ciliopathy. Affected individuals typically have some type of intestinal atresia, variable ocular abnormalities, microcephaly, and sometimes involvement of other systems, including renal and cardiac. In some cases, the condition is lethal in early life, whereas other patients show normal survival with or without mild cognitive impairment (summary by Filges et al., 2016).

Medium match RUBINSTEIN-TAYBI SYNDROME DUE TO EP300 HAPLOINSUFFICIENCY

Rubinstein-Taybi syndrome (RSTS) is a multiple congenital anomaly syndrome characterized by mental retardation, postnatal growth deficiency, microcephaly, broad thumbs and halluces, and dysmorphic facial features. The classic facial appearance is striking, with highly arched eyebrows, long eyelashes, downslanting palpebral fissures, broad nasal bridge, beaked nose with the nasal septum, highly arched palate, mild micrognathia, and characteristic grimacing or abnormal smile (Rubinstein and Taybi, 1963; review by Hennekam, 2006).About 50 to 70% of patients have RSTS1 due to mutation in the CREBBP gene (OMIM ). RSTS2 is much less common, and about 3% of patients have mutations in the EP300 gene. RSTS2 appears to be associated with a milder phenotype than RSTS1. Patients with RSTS2 have less severe facial dysmorphism and better cognitive function, but may have more severe microcephaly and malformation of facial bone structures compared to those with RSTS1 (Bartsch et al., 2010).For a discussion of genetic heterogeneity of Rubinstein-Taybi syndrome, see RSTS1 (OMIM ).

Medium match XERODERMA PIGMENTOSUM, COMPLEMENTATION GROUP F; XPF

Xeroderma pigmentosum is an autosomal recessive disorder characterized by sun sensitivity and increased skin sensitivity to UV light, as well as an increased risk of skin cancer associated with a defect in nucleotide excision repair (NER). The XPF form of XP is usually relatively mild compared to other forms. Patients with XPF tend to have later onset of skin cancer. Some patients with XPF may develop neurologic impairment or growth defects, and are then classified as having Cockayne syndrome (summary by Kashiyama et al., 2013).For a general phenotypic description and a discussion of genetic heterogeneity of xeroderma pigmentosa, see XPA (OMIM ), and of Cockayne syndrome, see CSA (OMIM ).

Medium match AUTOSOMAL RECESSIVE SPASTIC PARAPLEGIA TYPE 20

Autosomal recessive spastic paraplegia type 20 (SPG20) is a type of complex hereditary spastic paraplegia characterized by an onset in infancy of progressive spastic paraparesis associated with distal amyotrophy, psuedobulbar palsy, motor and cognitive delays, mild cerebellar signs (dysarthria, dysdiadochokinesia, mild intention tremor), short stature and subtle skeletal abnormalities (pes cavus, mild talipes equinovarus, kyphoscoliosis). SPG20 is due to mutations in the SPG20 gene (13q13.1), which encodes the protein spartin.
