<div class="spaceAbove">PORCN-related developmental disorders include a spectrum of highly variable multisystem disorders caused by developmental abnormalities in mesodermal and ectodermal structures primarily involving the skin, limbs, eyes, and face. The manifestations vary among affected individuals, and many have only a subset of the characteristic features. Skin manifestations present at birth include atrophic and hypoplastic areas of skin; cutis aplasia; fat nodules in the dermis manifesting as soft, yellow-pink cutaneous nodules; and pigmentary changes. Verrucous papillomas of the skin and mucous membranes may appear later. The nails can be ridged, dysplastic, or hypoplastic; hair can be sparse or absent. Limb malformations include oligo- and syndactyly and split hand/foot. Developmental abnormalities of the eye can include anophthalmia/microphthalmia, iris and chorioretinal coloboma, and lacrimal duct abnormalities. Craniofacial findings can include facial asymmetry, notched alae nasi, cleft lip and palate, pointed chin, and small, underfolded pinnae. Dental anomalies can include hypodontia, enamel defects, and/or abnormally shaped teeth. Occasional findings include abdominal wall defects, diaphragmatic hernia, and renal anomalies. Psychomotor development is usually normal; some individuals have cognitive impairment and/or behavioral issues.</div>

<div class="spaceAbove">Craniofrontonasal syndrome is an X-linked developmental disorder that shows paradoxically greater severity in heterozygous females than in hemizygous males. Females have frontonasal dysplasia, craniofacial asymmetry, craniosynostosis, bifid nasal tip, grooved nails, wiry hair, and abnormalities of the thoracic skeleton, whereas males typically show only hypertelorism (Twigg et al., 2004; Wieland et al., 2004).</div>

<div class="spaceAbove">Holt-Oram syndrome (HOS) is characterized by upper-limb defects, congenital heart malformation, and cardiac conduction disease. Upper-limb malformations may be unilateral, bilateral/symmetric, or bilateral/asymmetric and can range from triphalangeal or absent thumb(s) to phocomelia. Other upper-limb malformations can include unequal arm length caused by aplasia or hypoplasia of the radius, fusion or anomalous development of the carpal and thenar bones, abnormal forearm pronation and supination, abnormal opposition of the thumb, sloping shoulders, and restriction of shoulder joint movement. An abnormal carpal bone is present in all affected individuals and may be the only evidence of disease. A congenital heart malformation is present in 75% of individuals with HOS and most commonly involves the septum. Atrial septal defect and ventricular septal defect can vary in number, size, and location. Complex congenital heart malformations can also occur in individuals with HOS. Individuals with HOS with or without a congenital heart malformation are at risk for cardiac conduction disease. While individuals may present at birth with sinus bradycardia and first-degree atrioventricular (AV) block, AV block can progress unpredictably to a higher grade including complete heart block with and without atrial fibrillation.</div>

Developmental delay, intellectual disability, or seizures appear to be uncommon manifestations (~&lt;10%) of GCPS and may be more common in individuals with large (&gt;300-kb) deletions that encompass GLI3.

<div class="spaceAbove">EEM syndrome (EEMS) denotes a disorder characterized by ectodermal dysplasia, ectrodactyly, and macular dystrophy. The ectodermal dysplasia consists of hypotrichosis affecting scalp hair, eyebrows, and eyelashes, with partial anodontia. Different degrees of absence deformities as well as syndactyly have been described, the hands often being more severely affected than the feet. The retinal lesion appears as a central geographic atrophy of the retinal pigment epithelium and choriocapillary layer of the macular area with coarse hyperpigmentations and sparing of the larger choroidal vessels (summary by Kjaer et al., 2005).</div>

<div class="spaceAbove">Although both preaxial polydactyly and syndactyly are cardinal features of this malformation, it is classified as a form of polydactyly because syndactyly does not occur in the absence of polydactyly (McClintic, 1935), the opposite not being true. On the other hand, polysyndactyly is here classified as a type of syndactyly because polydactyly (of the third or fourth fingers and fifth toes) does not occur in the absence of syndactyly. The thumb shows only the mildest degree of duplication, and syndactyly of various degrees affects fingers 3 and 4. The foot malformation is more constant and consists of duplication of part or all of the first or second toes and syndactyly affects all of the toes, especially the second and third.</div>

Developmental delays. Often these findings are accompanied by episodic tachypnea or apnea and/or atypical eye movements. In general, the breathing abnormalities improve with age, truncal ataxia develops over time, and acquisition of gross motor milestones is delayed. Cognitive abilities are variable, ranging from severe intellectual disability to normal. Additional findings can include retinal dystrophy, renal disease, ocular colobomas, occipital encephalocele, hepatic fibrosis, polydactyly, oral hamartomas, and endocrine abnormalities. Both intra- and interfamilial variation are seen.</div>

The more severe features of classic SPD, involving 3/4 synpolydactyly in the hands and 4/5 synpolydactyly in the feet, also occur, but at reduced penetrance. This foot phenotype is not seen in patients with classic SPD due to HOXD13 polyalanine tract expansions (Goodman et al., 1998).&#13; Malik (2012) reviewed the syndactylies, noting that the extreme phenotypic heterogeneity observed in SPD families consists of approximately 18 clinical variants that can be 'lumped' into 3 categories: typical SPD features, minor variants, and unusual phenotypes.&#13; Genetic Heterogeneity of Synpolydactyly&#13; See also SPD2 (608180), caused by mutation in the fibulin-1 gene (FBLN1; 135820) on chromosome 22q13, and SPD3 (610234), which has been mapped to chromosome 14q11.2-q12.</div>
