It is characterized by skull (craniosynostosis and poorly mineralized cranial vault), dysmorphic (ocular hypertelorism, palpebral fissure anomalies, micrognathia cleft lip and/or high arched palate and small and low set/rotated ears) and limb (brachydactyly, syndactyly and clinodactyly) anomalies, associated with mild-to-moderate intellectual deficit and short stature. |

| A heterogeneous group of endocrine disorders with characteristics of normal renal function and resistance to the action of parathyroid hormone (PTH), manifesting with hypocalcaemia, hyperphosphataemia and elevated PTH levels and that includes the subtypes PHP type 1a (PHP-1a) , PHP type 1b (PHP-1b), PHP type 1c (PHP-1c), PHP type 2 (PHP-2) and pseudopseudohypoparathyroidism (PPHP). PHP-1a, PPHP, and PHP-1b are all due to molecular defects in the same locus of the GNAS (20q13.2-q13.3) gene coding the alpha sub-unit of the stimulatory G protein. PHP can be sporadic or inherited autosomal dominantly with parental imprinting. |

| Pseudohypoparathyroidism type 1B (PHP-1b) is a type of pseudohypoparathyroidism (PHP) characterized by localized resistance to parathyroid hormone (PTH) mainly in the renal tissues which manifests with hypocalcemia, hyperphosphatemia and elevated PTH levels. About 60-70% of patients also present with elevated TSH levels due to TSH resistance. |

| A type of pseudohypoparathyroidism with characteristics of resistance to parathyroid hormone (PTH), which manifests with hypocalcaemia, hyperphosphataemia and elevated PTH levels, absence of Albright's hereditary osteodystrophy and normal expression of the Gs protein with a normal urinary cAMP response. To date no specific genetic alteration responsible for this disorder has been detected. It has been hypothesised that in most cases it may be an acquired defect secondary to vitamin D deficiency such as in misdiagnosed secondary renal hyperparathyroidism. |

Usually, only the central retina is involved, however some cases of more widespread rod and cone anomalies have been reported. Rare additional features include empty sella turcica, impaired olfaction, renal infections, hematuria and recurrent miscarriages. |

| A rare genetic cerebral small vessel disease characterized by progressive loss of visual acuity due to retinal vasculopathy, in combination with more variable neurological signs and symptoms including stroke, cognitive decline, migraine-like headaches, and seizures, among others, typically beginning in middle age. Psychiatric features such as depression and anxiety may also occur. Systemic vascular involvement with Raynaud phenomenon, micronodular liver cirrhosis, and glomerular kidney dysfunction is present in a subset of patients. |
