    Co-Occurrence of Sotos Syndrome and Mayer-Rokitansky-Küster-Hauser (MRKH) Syndrome in 2 Patients
    (Oxford University Press, 2025-02-11) Mustafa, Manahil; Mitscher, Mary K.; Johnson, Nancy B.; Fuqua, John S.; Pediatrics, School of Medicine
    Sotos syndrome is an autosomal dominant condition caused by a pathogenic variant of NSD1 and characterized by a distinctive facial appearance, learning disability, and overgrowth. Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a congenital disorder characterized by agenesis or aplasia of the uterus and upper part of the vagina in females with a normal female karyotype. The coexistence of the 2 syndromes has been reported only twice to date. We describe 2 girls with Sotos syndrome who presented with primary amenorrhea. The patient in case 1 had central precocious puberty diagnosed at age 6.5 years, which was appropriately managed for 2 years. The patient in case 2 had congenital hypothyroidism due to thyroid aplasia, treated with levothyroxine. Investigations in both girls revealed normal gonadotropin and estradiol levels. Pelvic ultrasound and magnetic resonance imaging showed absence of the uterus and the presence of normal ovaries. Based on these findings, both patients were diagnosed with müllerian agenesis/MRKH. The presence of Sotos and MRKH syndromes in these 2 patients, along with the 2 previously documented cases, might be coincidental. However, with 4 reported cases, the possibility exists for a rare link between Sotos syndrome and MRKH. Additionally, the psychosocial effect of infertility should not be underestimated.
