ENPP1 deficiency causing gen arterial calcifcn of infancy

This code identifies a rare genetic disorder, ENPP1 deficiency, which leads to widespread calcification of arteries throughout the body, typically presenting in infancy. This condition is characterized by arterial stiffening and narrowing, often resulting in severe cardiovascular complications.

Apply this code for patients diagnosed with generalized arterial calcification of infancy (GACI) specifically confirmed to be caused by a pathogenic variant in the ENPP1 gene. Documentation should clearly state the diagnosis of GACI and specify the underlying ENPP1 deficiency, often supported by genetic testing results.

• Ensure genetic testing or clinical diagnosis explicitly links GACI to ENPP1 deficiency.
• Do not use for other forms of arterial calcification not attributed to ENPP1 deficiency.
• Consider sequencing with codes for associated cardiovascular manifestations, such as heart failure or hypertension, if present.
