Sanger sequencing results show mutations in DGAT1 detected in the proband’s family. a Chromatogram showing the proband with a heterozygous mutation at chr8:145541376, c.895-1G > A. b Chromatogram showing the proband’s father carrying the same heterozygous mutation, c.895-1G > A. c Chromatogram showing the proband’s mother with no mutation at this site. d Chromatogram showing the proband with another heterozygous mutation at chr8:145541757, c.751 + 1G > C. e Chromatogram showing the proband’s father with no mutation at this site. f Chromatogram showing the proband’s mother carrying the same heterozygous mutation, c.751 + 1G > C
