Case Report: A rare case of Noonan syndrome with multiple lentigines manifesting as cardiac enlargement
Noonan syndrome with multiple lentigines (NSML) is a rare autosomal dominant disorder, primarily caused by variants in the PTPN11 gene. Characterized by multiple lentigines, hypertelorism, short stature, and hearing loss, its common cardiac manifestations include pulmonary stenosis, hypertrophic car...

| Summary: | Noonan syndrome with multiple lentigines (NSML) is a rare autosomal dominant disorder, primarily caused by variants in the PTPN11 gene. Characterized by multiple lentigines, hypertelorism, short stature, and hearing loss, its common cardiac manifestations include pulmonary stenosis, hypertrophic cardiomyopathy (HCM), atrial septal defect, and left-sided heart lesions. We report a 58-year-old female diagnosed with NSML presenting with bilateral atrial and ventricular chamber enlargement and atrial fibrillation, which are uncommon cardiac phenotypes of NSML. |
