    Summary

    This study describes a patient with mosaic trisomy 7, a genetic condition, who exhibited features of Potter syndrome. The findings suggest a potential link between trisomy 7 and Potter syndrome development.

    Area of Science:

    • Genetics
    • Developmental Biology
    • Pediatrics

    Background:

    • Potter syndrome is a rare condition characterized by specific physical anomalies, primarily renal abnormalities.
    • Trisomy 7, the presence of an extra copy of chromosome 7, can lead to various developmental issues.

    Observation:

    • A neonate presented with features consistent with Potter syndrome, including pulmonary hypoplasia and renal agenesis.
    • The patient also displayed dysmorphic features such as low-set ears, a flattened nasal bridge, and rocker-bottom feet.
    • Cytogenetic analysis revealed mosaic trisomy 7, with 12% of skin cells having an extra chromosome 7.

    Findings:

    • The patient's demise was attributed to respiratory insufficiency secondary to pulmonary hypoplasia.
    • Autopsy confirmed renal agenesis, a key feature of Potter syndrome.
    • The presence of mosaic trisomy 7 in this patient with Potter syndrome features warrants further investigation.

    Implications:

    • This case suggests a potential correlation between mosaic trisomy 7 and the development of Potter syndrome.
    • Further research is needed to elucidate the specific mechanisms linking trisomy 7 to renal and pulmonary development.
    • Understanding this association may aid in early diagnosis and genetic counseling for affected families.
