Pseudohypoparathyroidism (PHP) is a rare Genetic Disorder where the body's tissues fail to respond to Parathyroid Hormone, despite normal hormone levels. This resistance leads to low blood Calcium and high Phosphate, causing a range of symptoms. PHP is classified into several types, primarily Type 1A (often linked to Albright's Syndrome), Type 1B, and Type 2, each with varying genetic causes and clinical presentations.
