The patient, a 10-month-old baby girl had dysmorphic facial features as well as neuromotor retardation, congenital hypothyroidism, atrial septal defect (ASD), white matter atrophy in cranial MRI, grade 2 dilatation in pelvicalyceal system of the left kidney, and bilateral ureteral reflux. In peripheral blood chromosome analysis 46, XX, dup(4) (q21q35) karyotype was detected. In FISH analysis using 4p/4q subtelomeric probe; 3 signals for 4 q region and 2 signals for 4p region were observed. In chromosome analyses of her healthy parents, no anomaly was detected. Herein we present a case of de novo partial distal trisomy 4q syndrome to contribute to the literature since it is rarely seen and this is the first patient with partial trisomy distal 4q syndrome presented with chronic cholecystitis and the second patient with hypothyroidism.eninfo:eu-repo/semantics/closedAccessBilateral membranous choanal atresiaDistal partial trisomy 4qChronic cholecystitisCongenital hypothyroidismChoanal atresiaLimbDuplication 4qDefectsBiotechnology & applied microbiologyResearch & experimental medicineGenetics & heredityMedical ethicsArticle0003489560000112-s2.0-8492332429542342825425804022Biotechnology & applied microbiologyMedicine, research & experimentalGenetics & heredityMedical ethicsChromosome 4Q- Syndrome; Trisomy; DeletionArticleBrain atrophyCase reportChoana atresiaChromosome analysisChronic cholecystitisCongenital hypothyroidismCorpus callosumFace dysmorphiaFemaleFluorescence in situ hybridizationHeart atrium septum defectHumanHypothyroidismInfantKidney scintiscanningNuclear magnetic resonance imagingPartial trisomy 4Partial trisomy distal 4qVesicoureteral refluxWhite matter
