Abstract

VALLEJO-URREGO, Michael A.; PARRA-MORALES, Alejandra M.  and  GONZALEZ, Adriana. HDR syndrome in a Colombian woman with a genital tract malformation: First case report in Latin America. Rev. salud pública [online]. 2018, vol.20, n.5, pp.637-640. ISSN 0124-0064.  http://dx.doi.org/10.15446/rsap.v20n5.71057.

Objectives

Hypoparathyroidism, sensorineural deafness and renal disease (HDR) syndrome, also known as Barakat syndrome, is an autosomal dominant transmission hereditary disease with a wide range of penetrance and expressivity. Haploinsufficiency of the GATA3 two finger zinc transcription factor is believed to be its cause. This is the first time this orphan disease is reported in Latin America, so the publishing of this report is expected to raise awareness on these types of syndrome, that are usually underdiagnosed in our region, which in turn causes an increase in the years lost to disability (YLDs) rates, as well as higher costs to be assumed by public health systems.

Methods

A 36-year-old Colombian woman diagnosed with parathyroid gland agenesis was referred from the Endocrinology Service to the Outpatient Service. According to her medical record, in the past she had developed hypocalcaemia, left renal agenesis, hypoparathyroidism, bicornate uterus and sensorineural hearing loss. Through a genetic analysis a pathological mutation on the short arm of the GATA 3 gen (c.404dupC, p Ala136 GlyfsTER 167) was confirmed, which led to a HDR syndrome diagnosis.

Discussion

This case proves that there is a possibility that mutations described in other continents may be developed by individuals from our region. Regardless of ethnicity, Barakat syndrome should be considered as a possible diagnosis in patients presenting the typical triad that has been described for this condition, since there could be underdiagnosis of this disease in Latin-America due to the lack of knowledge on this condition in said region, and that genetic counseling in these patients is of great importance for the implications of the syndrome in future generations.
