Figure

  • Fig. 1 Pathogenic CHD7 variant identified as the genetic cause of CS in an Indonesian patient. (A) Heterozygous nucleotide substitution at NM_017780.3:c.7234G>T identified by NGS. (B) Sanger sequencing confirmed a de-novo heterozygous nucleotide substitution (c.7234G>T) in exon 34 of CHD7. This change resulted in a premature stop codon (p.Glu2412Ter).Abbreviations: CS, CHARGE syndrome; NGS, next-generation sequencing.
