Unilateral Multicystic Dysplastic Kidney in a Fetus Associated With Parental Genetic and Environmental Risk Factors: A Case Report.

Multicystic dysplastic kidney (MCDK) is a congenital renal anomaly identified on prenatal ultrasound. They often arise sporadically and unilaterally. Our case involves an isolated unilateral MCDK in a fetus born to a mother with generalized anxiety disorder (GAD), obsessive-compulsive disorder (OCD), and gastroesophageal reflux disease (GERD), with the father having chronic occupational lead exposure and a congenital disorder of glycosylation type 1A (PMM2-CDG). Our case highlights the multifactorial etiology of renal dysplasia and its potential role of glycosylation defects and environmental toxicity in abnormal kidney development. Contributions from genetic, environmental, and metabolic influences during nephrogenesis contribute to MCDK.
