Abstract:
OBJECTIVETo carry out mutation analysis for a Chinese family affected with Escobar syndrome.
METHODSWhole exome sequencing (WES) was employed to detect potential mutation in the proband. Suspected mutations were validated by combining clinical data and result of Sanger sequencing.
RESULTSA homozygous missense mutation c.715C>T (p.R239C) was detected in the proband and his brother who was also affected. The parents and the daughters of the proband carried the heterozygous mutation c.715C>T, while other family members did not carry the mutation.
CONCLUSIONEscobar syndrome is a rare genetic disorder. WES is able to discover genetic mutation underlying this disorder and facilitate genetic counseling and prenatal diagnosis for the affected family.
