ABSTRACT
Renal tubulopathies are hereditary diseases due to mutations
on genes that codify transport proteins for specific elements,
resulting in a variety of alterations. Michelis-Castrillo
syndrome is a rare renal tubulopathie where alterations in
claudins 16 and 19, two tight junction proteins located in the
thick ascending loop of Henle and involved in the transport of
the dibasic ions calcium and magnesium resulting in hypercalciuria,
hypermagnesuria with nephrocalcinosis and renal
chronic insufficiency. We report an unborn baby girl in whom
nephrocalcinosis was detected in an ultrasound performed to
the gravid mother and due to the presence of placental calcification
and placental insufficiency it was decided to interrupt
the pregnancy. As newborn diagnosis and treatment were
established, we report initial findings, differential diagnosis,
established therapy and follow up for five years and review
of the recent literature.
