22q12.3-q13.1 microdeletion including SOX10 causes atypical Waardenburg syndrome

PURPOSE: To identify disease associated mutations in a male infant with congenital heart defects and heterochromia.

METHODS: A detailed clinical examination and routine laboratory tests were performed on the patient. We applied whole exome sequencing to identify the causal mutation on the proband and other family members.

RESULTS: The patient presented with severe congenital heart disease, strabismus, and pigment disturbances of the iris. We identified a deletion of 1.99 megabase [arr[hg19]22q12.3-13.1 (chr22:36656004-38643920) *1], including SOX10 and 13 RefSeq genes on this patient, which was associated with atypical Waardenburg syndrome.

CONCLUSION: Our results suggest that a deletion of 1.99 megabase (including SOX10) acts as a dominant pathogenic variant on the clinical presentations of this patient with atypical Waardenburg syndrome.
