De novo mutation and skewed X‐inactivation in girl with BCAP31 ‐related syndrome

Full genome analysis of a young girl with deafness, dystonia, central hypomyelination, refractory seizure, and fluctuating liver function impairment revealed a heterozygous, de novo variant in the BCAP31 gene on chromosome Xq28 (NM_001256447.2:c.92G>A), mutations of which caused the X-linked recessive severe neurologic disorder deafness, dystonia, and cerebral hypomyelination. Reverse transcription-polymerase chain reaction of the patient's...
