The umbilical cord contains an inexhaustible, noncontroversial source of stem cells for therapy. In the U.S., stem cells found in the umbilical cord are routinely placed into bio-hazardous waste after birth. Here, stem cells derived from human umbilical cord Wharton's Jelly, called umbilical cord matrix stem (UCMS) cells, are characterized. UCMS cells have(More)
We have evaluated a patient with Jacobsen syndrome. The patient presented with growth retardation, hypotonia, trigonocephaly, telecanthus, downward slanting palpebral fissures, bilateral inferior colobomas (of the iris, choroid, and retina), hydrocephalus, central nervous system (CNS) abnormalities, and an endocardial cushion defect, features commonly seen(More)
Campomelic dysplasia (CD) is a semilethal skeletal malformation syndrome with or without XY sex reversal. In addition to the multiple mutations found within the sex-determining region Y-related high-mobility group box gene (SOX9) on 17q24.3, several chromosome anomalies (translocations, inversions, and deletions) with breakpoints scattered over 1 Mb(More)
Recent studies have identified a (CCG)n repeat in the 5' untranslated region of the CBL2 protooncogene (11q23.3) and have demonstrated that expansion of this repeat causes expression of the folate-sensitive fragile site FRA11B. It has also been demonstrated that FRA11B is the site of breakage in some cases of Jacobsen syndrome (JS) involving terminal(More)
Pallister-Killian syndrome (PKS), a rare disorder, is characterized by tissue-limited or tissue-specific mosaicism. The characteristic chromosome abnormality associated with PKS is i(12p), which is seen predominantly in skin fibroblast cultures. Diagnosis of i(12p) has been carried out on buccal smears before and was shown to be an easy and feasible method.(More)
An infant presented with multiple congenital anomalies including a midline thoracoabdominal defect, absence of the sternum, ectopia cordis, right diaphragmatic hernia, right anophthalmia, left microphthalmia, incomplete bilateral cleft lip, and various limb defects including ectrodactyly of the right hand and left foot, and phocomelia of the right lower(More)
Approximately, 20 cases of interstitial deletions of 9q have been reported in the literature spanning the breakpoints from 9q21 to 9q34. Unlike the 9q subtelomeric deletions, the interstitial deletions do not demonstrate a specific recognizable phenotype, although the majority of patients had microcephaly. Lack of precise molecular delineation of the extent(More)
Familial transmission of del (18p) syndrome from a mother to her daughter is rare and has been reported only once before. We report a female patient referred to us at age 18 years because of mental retardation associated with short stature. Similar clinical features are also seen in her mother. Chromosome analysis revealed a 46,XX, del (18) (p11.2)(More)
Chromosome deletions involving 1p36 are the most common known terminal rearrangements occurring at a frequency of approximately 1 in 5,000 live births. In contrast, duplications of the same region have been reported rarely. We describe a familial rearrangement der(1)del(1)(p36.33)dup(1)(p36.33p36.22) identified in a mother, daughter, and son. These(More)
