ABSTRACT
Cerebral cavernous malformations (CCMs) of the central nervous system arise sporadically or secondary to genomic variation. Established genetic etiologies include deleterious variants in KRIT1 (CCM1), malcavernin (CCM2), and PDCD10 (CCM3). KRIT1-related disease has not been described in conjunction with lymphatic defects, although lymphatic defects with abnormal endothelial cell junctions have been observed in mice deficient in HEG1-KRIT1 signaling. We report a proband with CCMs, multiple chylous mesenteric cysts, and chylous ascites with leaky lymphatic vasculature. Clinical short-read exome sequencing detected a disease-associated KRIT1 variant (NM_194456.1c.[1927C>T];[=], p.(Gln643*)). We postulate an expansion of KRIT1-related disease to include lymphatic malformations and lymphatic endothelial dysfunction.
