Low match CRANIOSYNOSTOSIS 7; CRS7

Craniosynostosis is a primary abnormality of skull growth involving premature fusion of the cranial sutures such that the growth velocity of the skull often cannot match that of the developing brain. This produces skull deformity and, in some cases, raises intracranial pressure, which must be treated promptly to avoid permanent neurodevelopmental disability (summary by Fitzpatrick, 2013).For a discussion of genetic heterogeneity of craniosynostosis, see CRS1 (OMIM ).

Low match NEPHRONOPHTHISIS 20; NPHP20

Nephronophthisis-20 is an autosomal recessive tubulointerstitial nephritis characterized by progressive renal fibrosis resulting in end-stage renal failure. The age at onset is relatively late compared to other forms of NPHP, and patients develop end-stage renal disease in the second or third decades. Unlike most other forms of NPHP, NPHP20 does not have features of a ciliopathy and patients do not appear to have extrarenal manifestations (summary by Macia et al., 2017).For a general phenotypic description and a discussion of genetic heterogeneity of nephronophthisis, see NPHP1 (OMIM ).

Low match NEPHRONOPHTHISIS 18; NPHP18

Nephronophthisis-18 is an autosomal recessive disorder characterized by chronic tubulointerstitial nephritis resulting in end-stage renal disease in early childhood. Extrarenal manifestations, including intellectual disability or liver changes, may occur in some patients (summary by Failler et al., 2014).For a general phenotypic description and a discussion of genetic heterogeneity of nephronophthisis, see NPHP1 (OMIM ).

VCRL2 is an autosomal recessive congenital malformation syndrome characterized by vertebral segmentation abnormalities, congenital cardiac defects, renal, and distal mild limb defects.

Intellectual developmental disorder with neuropsychiatric features is an autosomal recessive disorder characterized by moderate intellectual disability, relatively mild seizures, and neuropsychiatric abnormalities, such as anxiety, obsessive-compulsive behavior, and autistic features. Mild facial dysmorphic features may also be present (summary by Srour et al., 2017).

Low match HYPERPROLINEMIA, TYPE I; HYRPRO1

Phang et al. (2001) noted that prospective studies of HPI probands identified through newborn screening as well as reports of several families have suggested that it is a metabolic disorder not clearly associated with clinical manifestations. Phang et al. (2001) concluded that HPI is a relatively benign condition in most individuals under most circumstances. However, other reports have suggested that some patients have a severe phenotype with neurologic manifestations, including epilepsy and mental retardation (Jacquet et al., 2003). Genetic Heterogeneity of HyperprolinemiaSee also hyperprolinemia type II (HYRPRO2 ), which is caused by mutation in the gene encoding pyrroline-5-carboxylate dehydrogenase (P5CDH, ALDH4A1; {606811}) on chromosome 1p36.

Low match SHORT-RIB THORACIC DYSPLASIA 11 WITH OR WITHOUT POLYDACTYLY; SRTD11

Short-rib thoracic dysplasia (SRTD) with or without polydactyly refers to a group of autosomal recessive skeletal ciliopathies that are characterized by a constricted thoracic cage, short ribs, shortened tubular bones, and a 'trident' appearance of the acetabular roof. SRTD encompasses Ellis-van Creveld syndrome (EVC) and the disorders previously designated as Jeune syndrome or asphyxiating thoracic dystrophy (ATD), short rib-polydactyly syndrome (SRPS), and Mainzer-Saldino syndrome (MZSDS). Polydactyly is variably present, and there is phenotypic overlap in the various forms of SRTDs, which differ by visceral malformation and metaphyseal appearance. Nonskeletal involvement can include cleft lip/palate as well as anomalies of major organs such as the brain, eye, heart, kidneys, liver, pancreas, intestines, and genitalia. Some forms of SRTD are lethal in the neonatal period due to respiratory insufficiency secondary to a severely restricted thoracic cage, whereas others are compatible with life (summary by Huber and Cormier-Daire, 2012 and Schmidts et al., 2013).There is phenotypic overlap with the cranioectodermal dysplasias (see CED1, {218330}).For a discussion of genetic heterogeneity of short-rib thoracic dysplasia, see SRTD1 (OMIM ).
