  Chronically hypoparathyroid patients manifest with muscle cramps, pseudopapilledema, extrapyramidal signs, mental retardation and personality disturbances, as well as cataracts, dry rough skin, coarse brittle hair, alopecia and abnormal dentition(l). [indianpediatrics.net]

• Severe Osteoporosis

  The 2002 FDA approval of the recombinant form of parathyroid hormone 1-34 (Forteo , Teriparatide) for the treatment of severe osteoporosis has allowed this therapy to be used off-label for treatment of hypoparathyroidism both in the US and in Europe. [rarediseases.org]

• Long Arm

  X-linked recessive hypoparathyroidism is caused by mutations of a gene located on the long arm (q) of the X chromosome (Xq26-q27). This gene plays a critical role in the development of the parathyroid glands. [rarediseases.org]

• Suggestibility

  We found that in none of the 23 affected individuals was there absence of the parathyroid hormone gene or abnormal restriction patterns to suggest recognizable deletions, insertions, or rearrangements. [ncbi.nlm.nih.gov]

  These results indicate that four members of the family were affected, suggesting autosomal dominant inheritance. Brain CT revealed calcification of basal ganglia in the proband, her father and a younger sister, but not in her younger brother. [jstage.jst.go.jp]

Standard Therapies Treatment Treatment is aimed at raising calcium levels high enough to provide symptom relief without causing abnormally high levels of calcium excretion in the urine (hypercalciuria). [rarediseases.org]

Prognosis The regular monitoring required to ensure appropriate calcium levels means that the prognosis is challenging for many people. This may improve if synthetic PTH becomes widely available. [patient.info]

Etiology FIH may be due to an activating mutation of the calcium-sensing receptor ( CASR ) gene. This is the most common cause of genetic hypoparathyroidism and is transmitted as an autosomal dominant trait. [orpha.net]

As the patient had a second episode of hypocalcemia despite calcium supplements, other etiologies for this were sought for. [indianpediatrics.net]
