Pseudohypoparathyroidism

Is anyone here affected by, knows anybody affected by, or has a child affected by pseudohypoparathyroidism?

I found out after conception that the father has pseudohypoparathyroidism and am just now finding out the severity of it, which has a 50% chance of being inherited. Some unborn males affected don't make it to birth.

I'm curious for more information if anybody knows anything! Thank you!
