PG - 1199-1202 LID - 10.3760/cma.j.issn.1003-9406.2019.12.012 [doi] AB - OBJECTIVE: To carry out genetic testing for a boy presenting with mental retardation and hypoplasia. METHODS: Conventional karyotyping, fluorescence in situ hybridization (FISH) and single nucleotide polymorphism based array (SNP-array) were used to analyze the boy and his parents. RESULTS: SNP-array has detected a 25.7 Mb microduplication at 2q33.3q36.3 in the boy. Chromosomal karyotyping and FISH analysis indicated that his mother had a karyotype of 46,XX,ish ins(11;2) (p15;q33q36), and that the boy has carried an abnormal chromosome 11 derived from the maternal translocation. The karyotype of the boy was ascertained as 46,XY,ish der(11)ins(11;2) (p15;q33q36)mat. CONCLUSION: SNP-array combined with G-banding and FISH can delineate the cryptic translocation and is valuable for the assessment of recurrence risk for subsequent pregnancies.
