Clinical expression of Holt-Oram syndrome on the basis of own clinical experience considering prenatal diagnosis.

OBJECTIVES: Holt-Oram syndrome manifests with defects of upper limbs, pectoral girdle and cardiovascular system. The aim of this paper was to present complex clinical picture of the syndrome and its variable expression on the example of the family diagnosed genetically on the neonatal ward, after proband's prenatal examination.

MARETIAL AND METHODS: Nine family members were tested for TBX5 gene mutation.

RESULTS: Four of family members were diagnosed with Holt-Oram syndrome and five had correct genetic test results. The diagnosis allowed to identify a genetic risk family and enabled to provide them with genetic counselling.

CONCLUSIONS: Diagnosis of Holt-Oram syndrome is possible as early as in prenatal period and it can be verified by genetic tests.
