Abstract
BACKGROUND
We described the main features of an infant diagnosed with facial dysmorphic, language failure, intellectual disability and congenital malformations to strengthen our understanding of the disease. Currently, treatment is only rehabilitation and surgery for cleft lip and palate.
CASE SUMMARY
The proband was a 2-years-8-months-old girl. Familial history was negative for congenital malformations or intellectual disability. The patient had microcephaly, upward-slanting palpebral fissures, depressed nasal bridge, bulbous nose and bilateral cleft lip and palate. Brain magnetic resonance imaging showed cortical atrophy and band heterotopia. Her motor and intellectual development is delayed. A submicroscopic deletion in 11p13 involving the elongator acetyltransferase complex subunit 4 gene (ELP4) and a loss of heterozygosity in Xq25-q26.3 were detected.
CONCLUSION
There is no treatment for the ELP4 deletion caused by a submicroscopic 11p3 deletion. We describe a second case of deletion of the ELP4 gene without aniridia, which confirms the association between ELP4 gene with several defects and absence of this ocular defect. Additional clinical data in the deletion of the ELP4 gene as cleft palate, facial dysmorphism, and changes at level brain could be associated to this gene or be part of the effect of the recessives genes involved in the loss of heterozygosity region of Xq25-26.3.
Core Tip: We report a case diagnosed with submicroscopic 11p13 deletion. The main clinical characteristics and elongator acetyltransferase complex subunit 4 gene deletion, and treatments were assessed and a review of the related literature was performed. Very important, this is the second case of deletion of the elongator acetyltransferase complex subunit 4 gene without aniridia.
