In the following list you will find some of the most common rare diseases related to Delayed speech and language development and Dilatation that can help you solving undiagnosed cases.
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 ).

Most patients show neurologic abnormalities such as intellectual disability, seizures, hypotonia, and motor delay (summary by Ferri et al., 2014).

The phenotype includes the alternative clinical designation Walker-Warburg syndrome (WWS), which is associated with death in infancy. The disorder represents the most severe end of a phenotypic spectrum of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1), collectively known as 'dystroglycanopathies' (summary by Geis et al., 2013 and Riemersma et al., 2015).For a general phenotypic description and a discussion of genetic heterogeneity of muscular dystrophy-dystroglycanopathy type A, see MDDGA1 (OMIM ).
MUSCULAR DYSTROPHY-DYSTROGLYCANOPATHY (CONGENITAL WITH BRAIN AND EYE ANOMALIES), TYPE A, 9; MDDGA9 Is also known as walker-warburg syndrome or muscle-eye brain disease, dag1-related

Limb-girdle muscular dystrophies resulting from defective glycosylation of alpha-dystroglycan (DAG1 ) represent the mildest end of the phenotypic spectrum of muscular dystrophies collectively known as dystroglycanopathies. The limb-girdle phenotype is characterized by onset of muscular weakness apparent after ambulation is achieved; mental retardation and mild brain anomalies are variable (Balci et al., 2005; review by Godfrey et al., 2007). The most severe end of the phenotypic spectrum of dystroglycanopathies is represented by congenital muscular dystrophy-dystroglycanopathy with brain and eye anomalies (type A; see MDDGA1, {236670}), previously designated Walker-Warburg syndrome (WWS) or muscle-eye-brain disease (MEB), and the intermediate range of the spectrum is represented by congenital muscular dystrophy-dystroglycanopathy with or without mental retardation (type B; see MDDGB1, {613155}).
MUSCULAR DYSTROPHY-DYSTROGLYCANOPATHY (LIMB-GIRDLE), TYPE C, 1; MDDGC1 Is also known as muscular dystrophy, limb-girdle, type 2k;lgmd2k;lgmd2k; limb-girdle muscular dystrophy-intellectual disability syndrome

Some patients may have additional features, such as microcephaly, cardiac dysfunction, seizures, or cerebellar hypoplasia. It is part of a group of similar disorders resulting from defective glycosylation of alpha-dystroglycan (DAG1 ), collectively known as 'dystroglycanopathies' (summary by Carss et al., 2013).For a discussion of genetic heterogeneity of congenital muscular dystrophy-dystroglycanopathy type B, see MDDGB1 (OMIM ).
MUSCULAR DYSTROPHY-DYSTROGLYCANOPATHY (CONGENITAL WITH MENTAL RETARDATION), TYPE B, 14; MDDGB14 Is also known as muscular dystrophy, congenital, gmppb-related

Most patients have hearing loss, and some may have global developmental delay (summary by Heidet et al., 2017).

Age at onset ranges from 3 to 30 years. The disorder is less severe than GM1-gangliosidosis types I and II (OMIM ). Type III shows extreme clinical variability, with some patients having only focal neurologic signs, such as dystonia, and others having more severe involvement with extrapyramidal signs and mental retardation. GLB1 enzymatic activity usually ranges from approximately 4 to 10% of control values (Suzuki et al., 2001).
GM1-GANGLIOSIDOSIS, TYPE III Is also known as gangliosidosis, generalized gm1, adult type, gangliosidosis, generalized gm1, chronic type, gangliosidosis, generalized gm1, type iii, gangliosidosis, generalized gm1, type 3;adult-onset gm1 gangliosidosis

The most severely affected patients show developmental delay and mental retardation, but there are differing levels of severity and some patients may have comparatively mild disease (Bedilu et al., 2002) The disorder was first described in goats (Jones and Dawson, 1981), who have a more severe neurodegenerative disorder than that seen in humans.
