    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.

    Müllerian anomalies and endometriosis: associations and phenotypic variations
    (Springer Nature, 2024-12-19) Bhamidipaty-Pelosi, Surya; Kyei-Barffour, Isaac; Volpert, Marianna; O’Neill, Nora; Grimshaw, Alyssa; Eriksson, Lars; Vash-Margita, Alla; Pelosi, Emanuele; Biochemistry and Molecular Biology, School of Medicine
    Müllerian anomalies are congenital conditions characterized by the incomplete development of the female reproductive tract. Women affected by Müllerian anomalies often display additional malformations of the renal, skeletal, and cardiovascular system, and are at a higher risk for infertility and adverse pregnancy outcomes. Several Müllerian anomalies have been reported in association with endometriosis, but it is unclear if all classes or anatomical variations are associated with the disease. Most importantly, both Müllerian anomalies and endometriosis can manifest with a wide degree of variability, adding further complexity to their poorly defined relationship. Retrograde menstruation occurring in obstructive Müllerian anomalies is a well-accepted mechanism for the development of endometriosis. However, endometriosis can occur following surgical correction of the anomaly or in the absence of obstruction. This suggests that other mechanisms may be involved, although the specific pathogenesis remains elusive. This review provides a comprehensive summary of the current state of clinical research on endometriosis in Müllerian anomalies. This review also highlights research and knowledge gaps, informing the development of future experimental designs to address current limitations including heterogeneity of phenotypes, variable comorbidities, and lack of genetic information.
