We used whole exome sequencing (WES) in the family to examine the genetic cause of the disease.Results: The proband presented with skin pigmentation, hypertriglyceridemia and diabetes. WES identified a previously unreported compound heterozygous mutation in the BSCL2 (c.545_546insCCG heterozygous mutation and exon 3 heterozygous deletion) in the proband. His mother is a heterozygous carrier of the c.545_546insCCG mutation and his father and brother are carriers of the exon 3 heterozygous deletion.Conclusion: Compound heterozygous mutation of the BSCL2 (new c.545_546insCCG heterozygous mutation and new exon 3 heterozygous deletion) was detected in the proband with characteristic clinical manifestations of CGL2.Keywords: congenital generalized lipodystrophy, pigmentation, hypertriglyceridemia, diabetes, BSCL2 mutation, whole exome sequencing |
