Comment on list classification: Rating Amber with watchlist tag - 2 unrelated cases (2 Tunisian sibs, 1 Dutch man) have been identified with homozygous variants in this gene and severe pulmonary arterial hypertension. RNA sequencing demonstrated aberrant splicing resulting in the complete absence of the CAPNS1 protein in affected patients. Additional case required before promotion to Green.
