GACI/ARHR2 Awareness Day is February 1st every year

Around the world, Rare Disease Day is acknowledged on the last day of February, a month known for having a ‘rare’ number of days.

We are kicking off the ‘rare’ month of February with the second annual GACI/ARHR2 Awareness Day on February 1, 2021.

Please join us in spreading awareness of the ultra-rare conditions of Generalized Arterial Calcification of Infancy (GACI) and Autosomal Recessive Hypophosphatemic Rickets Type 2 (ARHR2).

Why is it important to have an awareness day for GACI/ARHR2?

GACI is a rare disease which occurs in roughly 1/200,000 births.  The survival statistics for GACI are currently estimated to be around 50%, with the most critical period being the child’s first 6 months of life. The length of time from symptom onset to proper diagnosis of a rare disease is currently 4.8 years.  Most doctors have never even heard of Generalized Arterial Calcification of Infancy….and an infant born with GACI does not have 4.8 years to wait for proper diagnosis.

Those who survive GACI may develop a rare form of rickets known as ARHR2.  This can result in bone and joint pain, bone deformities, dental problems, calcification of ligaments and short stature.

Early diagnosis leads to earlier treatment options. Early diagnosis saves lives.  So we are actively working to spread our message.  This is our motivation for having GACI/ARHR2 Awareness Day!


  • GACI/ARHR2 are ultra-rare conditions.  GACI is estimated to occur in roughly 1/200,000 births.
  • Survival statistics are estimated to be around 50%.
  • GACI Type 1 is caused by mutations in the ENPP1 gene, also referred to as ENPP1 Deficiency.
  • ENPP1 Deficiency can also cause Autosomal Recessive Hypophosphatemic Rickets Type 2.
  • GACI Type 2 is caused by mutations in the ABCC6 gene, also referred to as ABCC6 Deficiency.
  • ABCC6 Deficiency can also cause Pseudoxanthoma Elasticum.
  • ENPP1 and ABCC6 Deficiencies are LIFELONG conditions that can cause a broad range of complications throughout a patient’s lifetime.
