Brief Summary
To assess the diagnostic yield of Sanger sequencing for ACTG2 and FLNA genes evaluation on blood or saliva sample in patients with idiopathic CIPO in which high-resolution esophageal manometry (HRM) shows reduced (DCI \<450 mmHg\*s\*cm) or absent distal esophageal contractility.

Outcome Measures
Primary Outcomes (1)
The prevalence of mutations of ACTG2 or FLNA genes in a subgroup of patients with idiopathic CIPO with a myopathic phenotype revealed by reduced or absent distal esophageal contractility evaluated with high resolution esophageal manometry
October 2025-October 2026
Eligibility Criteria
Study participants will be selected from adult CIPO patients referred to and followed at our tertiary referral center during the study period.
You may qualify if:
- Age ≥ 18 years
- Male or female
- Primary chronic intestinal pseudo-obstruction (CIPO)
- Reduced (DCI \< 450 mmHg·s·cm) or absent distal esophageal contractility on high-resolution manometry (HRM)
You may not qualify if:
- Secondary CIPO
- Primary CIPO due to an autoimmune/inflammatory disorder, evidenced by the presence of any of the following antibodies:
- anti-Hu
- anti-GAD
- ASMA
- anti-gAChR
