Overview
Other diagnostic studies include genetic testing, platelet aggregation testing for Gsα defects and bone densitometry testing.
Other Diagnostic Studies
- Genetic testing may be helpful in the diagnosis of pseudohypoparathyroidism[1][2]
- Analysis of the GNAS1 gene can confirm diagnosis and identify the different variants of PHP
- Testing for paternal uniparental isodisomy of chromosome 20q or deletions in STX16 can also help in diagnosis of pseudohypoparathyroidism 1b
- Gsα defects can be diagnosed by assessment of variations in platelet aggregation responses reflecting a patient's genotype
- Pseudohypoparathyroidism type 1b associated bone disease can be evaluated with bone mineral density (BMD)
