"De Novo" Duplication Xq23→Xq26 of Paternal Origin in a Girl With a Mildly Affected PhenotypeGarcia-Heras, Jaime, Martin, Judith A., Day, Donald W., Scacheri, Peter, Witchel, Selma F. 27 June 1997 (has links)
We report a de novo dup(X)(q23→q26) in a 3-year-old girl with growth retardation, developmental delay, and minor anomalies. X-inactivation in lymphocytes by BRDU labeling showed the abnormal X was late replicating. The androgen receptor assay (HAR) demonstrated a skewed methylation (88.8%) of the paternal allele and a 11.2% methylation of the maternal allele. These data, which suggest the duplication was paternally inherited, are the first parental-origin identification of a duplication Xq. The mild phenotype of the patient may be related to the size and region of the duplication, the low percentage of a dup(X) active detected by the HAR assay, or a combination of these mechanisms. .
