Non-acquired combined pituitary hormone deficiency-sensorineural hearing loss-spine abnormalities syndrome is a rare, genetic, non-acquired, combined pituitary hormone deficiency disorder characterized by panhypopituitarism (with or without ACTH deficiency) associated with spine abnormalities, including frequent rigid cervical spine and short neck with limited rotation, and variable degrees of sensorineural hearing loss. The anterior pituitary gland is usually abnormal (typically hypoplastic) and rarely a mild developmental delay or intellectual disability may be associated.

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 ).

Autosomal recessive cutis laxa type II represents a spectrum of clinical entities with variable severity of cutis laxa, abnormal growth, developmental delay, and associated skeletal abnormalities. Aside from cutis laxa, persistent wide fontanels, frontal bossing, slight oxycephaly, downward-slanted palpebral fissures, reversed-V eyebrows, and dental caries are characteristic. Patients with ARCL2 can be divided into 2 major groups: ARCL2A, comprising those with a combined N- and O-linked glycosylation defect (CDG type II), and ARCL2B, those without a metabolic disorder (summary by Morava et al., 2009). Van Maldergem et al. (2008) concluded that ARCL2A should be considered more of a multisystem disorder with cobblestone-like brain dysgenesis manifesting as developmental delay and an epileptic neurodegenerative syndrome rather than purely a dermatologic disorder.For a phenotypic description and a discussion of genetic heterogeneity of autosomal recessive cutis laxa, see ARCL1A (OMIM ). Genetic Heterogeneity of Cutis Laxa Type IIARCL2A is caused by mutation in the ATP6V0A2 gene. ARCL2B (OMIM ) is caused by mutation in the PYCR1 gene (OMIM ). ARCL2C (OMIM ) is caused by mutation in the ATP6V1E1 gene (OMIM ). ARCL2D (OMIM ) is caused by mutation in the ATP6V1A gene (OMIM ).

Short stature-onychodysplasia-facial dysmorphism-hypotrichosis syndrome is a rare, genetic, primary bone dysplasia disorder characterized by severe pre- and post-natal short stature, facial dysmorphism (incl.dolicocephaly, long triangular face, tall forehead, down-slanting palpebral fissures, prominent nose, long philtrum, small ears), early-onset or postpubertal sparse, short hair and hypoplastic fingernails. Small hands with tapering fingers, bracydactyly and fifth-finger clinodactyly, as well as a high-pitched voice are also associated.

Vitamin D-dependent rickets type 2A (VDDR2A) is caused by a defect in the vitamin D receptor gene. This defect leads to an increase in the circulating ligand, 1,25-dihydroxyvitamin D3. Most patients have total alopecia in addition to rickets.VDDR2B (OMIM ) is a form of vitamin D-dependent rickets with a phenotype similar to VDDR2A but a normal vitamin D receptor, in which end-organ resistance to vitamin D has been shown to be caused by a nuclear ribonucleoprotein that interferes with the vitamin D receptor-DNA interaction.For a general phenotypic description and discussion of genetic heterogeneity of rickets due to disorders in vitamin D metabolism or action, see vitamin D-dependent rickets type 1A (VDDR1A ).

Autosomal recessive limb-girdle muscular dystrophy type 2S (LGMD2S) is a form of limb-girdle muscular dystrophy characterized by childhood-onset of progressive proximal muscle weakness (leading to reduced ambulation) with myalgia and fatigue, in addition to infantile hyperkinetic movements, truncal ataxia, and intellectual disability. Additional manifestations include scoliosis, hip dysplasia, and less commonly, ocular features (e.g. myopia, cataract) and seizures.

Singleton-Merten dysplasia is characterized by dental dysplasia, progressive calcification of the thoracic aorta with stenosis, osteoporosis and expansion of the marrow cavities in hand bones. Additional features included generalized muscle weakness and atrophy, and chronic psoriasiform skin eruptions. It has been reported in four unrelated patients (male and female) and in a family with multiple affected members (male).
