A case of recurrent hemorrhage due to localized gastric mucosal congestion from retrograde prolapse during severe retching is described. Historically, this condition may mimic the "Mallory-Weiss syndrome" and endoscopically, this lesion may be mistaken for "gastritis". This rarely recognized condition may be an explanation for some cases of cryptic hematemesis.

Cryptic unbalanced chromosome rearrangements in the telomeric bands of the chromosomes may constitute a significant cause of unexplained mental retardation with or without congenital anomalies. We report on a boy with a terminal deletion of the long arm of chromosome 13, combined with a partial duplication of the short arm of chromosome 20, owing to a cryptic balanced translocation in his father. The karyotype of the father was 46XY,t(13;20)(q34;p13). The propositus presented with severe mental and growth retardation, microcephaly, facial anomalies including ptosis of the right upper eyelid, a high nasal bridge, small palpebral fissures, and bilateral epicanthus, hypospadias, and scoliosis. A younger brother died at birth and had a low birth weight, hypospadias, and a horseshoe kidney. Repeated chromosome analyses with high resolution banding in the propositus and his parents were apparently normal. Chromosome painting eventually disclosed the cryptic translocation in the father with unbalanced karyotype in the propositus. The importance of additional FISH analysis in patients with unexplained mental retardation, physical anomalies, and apparently normal chromosomes is emphasized.

We report on the prenatal diagnosis of two sib female fetuses with a satellited short arm of chromosome 4 and a male fetus with a satellited long arm of chromosome X. The first two fetuses had a cryptic balanced translocation (4;15)(p16;p11.1) inherited from a mother carrying a satellited 4p and having an affected child with the Wolf-Hirschhorn syndrome. The third fetus had a satellited Xq, with a deletion of subtelomeric region of Xq. The mother was subsequently found to have the same satellited Xq but without the presence of a reciprocal translocation. She decided to continue the pregnancy. The proband with a satellited Xq manifested developmental delay, mental retardation, hypertelorism, ptosis of one eye, low-set ears, and hearing disturbance at age 6 months. Fluorescence in situ hybridization (FISH) with a specific telomeric or subtelomeric probe, and genetic marker analyses were used to confirm the diagnosis. Pregnant women with satellited non-acrocentric chromosomes are at risk for carrying fetuses with chromosome abnormalities. If the X chromosome is involved, the fetuses can be affected with X-linked recessive disorders including mental retardation. Detailed genetic counselling, cytogenetic studies, FISH and genetic marker analyses are useful in prenatal detection of abnormal chromosome rearrangements.

Monozygotic twin brothers are described who share clinical features which include: moderate mental retardation, short stature, macrocephaly, frontal bossing, ptosis, low-set ears, brachydactyly, 5th fingers clinodactyly, single palmar creases, cryptorchidism, and prelingual sensorineural deafness. One of the twins presented with mild cardiac dilatation and died at age 3(1/2) from cardiac arrest during an episode of acute respiratory infection. While chromosome analyses performed for both twins on peripheral blood showed apparently normal karyotypes, screening for all telomeric regions on the surviving propositus revealed a combination of partial 6p trisomy and partial 11q monosomy. A balanced reciprocal translocation was found in the father. The phenotype of the twins is most likely related to this cryptic chromosomal rearrangement. The fact that the phenotype in this family partially overlaps with some previously reported phenotypes is discussed.

Chromosomal abnormalities involving double partial monosomies are very rare. A female infant with non-mosaic monosomy 10p13-->10pter along with monosomy Xp11.4-->Xpter which arose de novo is described. The clinical manifestations of this patient included microcephaly, mild synophrys, short and down-slanted palpebral fissures, ptosis of the left eye, long eyelashes, a depressed nasal bridge, dysplastic ears, micrognathia, a short neck. sensorineural hearing impairment, and severe growth retardation. Left choanal atresia and laryngomalacia were detected by flexible fibroscopy. No signs of hypoparathyroidism or defective cellular immunity could be found. Fluorescence in situ hybridization (FISH) with whole-chromosome painting probes for chromosomes 10 and X was performed, which excluded the possibility of cryptic translocations of the involved chromosome segments. No submicroscopic chromosome 22q11 deletion could be found by FISH. Thus this very rare coexistence of double independent partial monosomies was confirmed. There are no previous reports of such concurrent double partial monosomies.

We report clinical, cytogenetic, and molecular cytogenetic studies on four patients with subtle or submicroscopic 7q36 deletions either of de novo origin or resulting from a cryptic parental translocation. Fluorescence in situ hybridization (FISH) studies indicated that in all four patients, the Sonic Hedgehog gene (SHH) and the homeobox gene HLXB9, among others, are comprised in the deletions. Besides mental retardation and short stature, all patients showed only minimal manifestations of the holoprosencephaly (HPE) spectrum and only one displayed symptoms of the Currarino syndrome. Patient 1 had a de novo 7q36.1-qter deletion and showed microcephaly, ptosis, sacral agenesis, tethered cord, but no structural brain anomaly. Patient 2 had a submicroscopic de novo 7q36 deletion detected by FISH, and showed facial and cerebral microsigns of the HPE spectrum. Patient 3 had a 7q36 deletion found by subtelomere FISH testing that was the unbalanced product of a subtle maternal 7q;10q translocation. She presented facial and ocular microsigns, but no structural abnormality of the brain. Patient 4 showed no specific syndromal pattern and was found to have a cryptic unbalanced de novo translocation of the terminal parts of chromosomes 7q and 9p by subtelomere FISH. Patients 2, 3, and 4 represent the first report of a de novo submicroscopic 7q36 deletion, the second report of a familial subtle translocation of 7q36, and the first report of an unbalanced de novo submicroscopic translocation of 7q36, respectively. Our results stress the importance of 7q36 deletion studies by FISH in patients with microsigns of the HPE spectrum.

Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare autosomal dominant disorder characterized by a complex dysgenesis of the eyelids and premature ovarian insufficiency. FOXL2 located at 3q22.3, encoding a forkhead transcription factor, is the only gene known to be responsible for BPES. We describe a patient diagnosed with BPES with atypical ovarian failure, characterized by normal levels of gonadotropins, who was found to have trisomy X as well as a translocation (3;11)(q22.3;q14.1). The translocation breakpoint at 3q22.3 is located upstream of the FOXL2 gene and most likely causes BPES by separating the FOXL2 transcription unit from its cis-regulatory sequences. By array analysis we detected mosaicism for the balanced and an unbalanced form of the translocation in blood cells. We propose mitotic recombination as the likely mechanism of the mosaicism formation. Mitotic recombination is a common phenomenon in human cells. Thus, we hypothesize that it may be one of the mechanisms responsible for cryptic imbalances and possible abnormal phenotypes in some carriers of balanced rearrangements.
