A de novo translocation (X;1)(q13.1;p36.33) was found in a 2-year-old girl with typical clinical features of X-linked anhidrotic ectodermal dysplasia (EDA). The breakpoint at Xql3.1 is approximately the same as has been described in 2 other EDA females with X;autosome translocations.

✦ Synopsis
We present here a historical documentation of a female with X-linked hypohidrotic ectodermal dysplasia (XHED) and a de novo X/9 chromosome translocation. The patient was verbally reported by Dr. P.L. J. Cook to the HGM conference in 1973, but was subsequently lost to follow up. We have since traced her and confirmed the diagnosis of XHED with moderately severe mental retardation. According to Dr. P. L. J. Cook's records, fibroblast cell line AnLy GMO 705, was derived from this patient. Another female with a de novo X/12 chromosome translocation and hypohidrotic ectodermal dysplasia was recently reported. In both cases, the X chromosome breakpoint appears to be at Xq13.1.

## Abstract X‐linked hypohidrotic ectodermal dysplasia (XLHED) is characterized by severe hypohidrosis, hypotrichosis, and hypodontia. The gene responsible for this pleiotropic syndrome (__ED1__) consists of 12 exons, 8 of them coding for a transmembrane protein (ectodysplasin‐A; EDA‐A) involved in

A case of X-autosome translocation was diagnosed prenatally [46,X,t(X;9)(p21.3∼ 22.1;q22]. We describe the use of fluorescence in situ hybridization (FISH) to estimate the integrity of the Duchenne muscular dystrophy (DMD) gene. X-inactivation studies were used as well to assess the probability of p
