Abstract:
OBJECTIVE:To assess the value of combined cytogenetic and molecular techniques for the prenatal diagnosis of a pregnant woman with intellectual disability (ID).
METHODS:The fetus and its parents were subjected to G-banding karyotyping analysis, single nucleotide polymorphism array (SNP-array) and fluorescence in situ hybridization (FISH) analysis.
RESULTS:G-banding karyotype analysis revealed that the woman has carried a chromosomal microdeletion 46,XX,del(11)(q24), and the fetus was a carrier of 46,XN,del(11)(q24)mat. Subsequent SNP-array and FISH analysis of the pregnant woman indicated that the microdeletion has mapped to 11q24.1-q25. Both the pregnant woman and her fetus were diagnosed with Jacobsen syndrome.
CONCLUSION:Combined use of cytogenetic and molecular genetic techniques can facilitate diagnosis of patients with intellectual disability.
