Abstract
Individuals with 3p deletion show a great clinical variability. Apparently, a 1.5-Mb terminal deletion, including the CRBN and CNTN4 genes, is sufficient to cause this syndrome. Partial trisomy 13q is a rare chromosomal abnormality with a variable phenotypic expression, but in most cases, patients have a phenotype resembling complete trisomy 13. The aim of the present study is to describe a 9-month-old Mexican male patient with 3p deletion/13q duplication and a novel clinical finding. He presented with facial dysmorphism and multiple congenital alterations. Echocardiogram revealed cardiac insufficiency with hypertrophic cardiomyopathy and pulmonary hypertension, not previously reported. Karyotype from the patient and his father were 46,XY,add(3)(p26) and 46,XY,t(3;13), respectively. Microarray assay of the proband exhibited an approximately 2.6-Mb loss at terminal 3p26.3 and a 27.7-Mb gain of the long arm in terminal chromosome 13 at q31.1q34. A chromosomal imbalance with a partial trisomy 13q31.1q34 and monosomy 3p26.3 of paternal origin were detected. Microarray assay of both parents were normal. The proband has a cardiomyopathy not previously reported. These data enrich the spectrum of clinical manifestations in 3p deletion/3q duplication chromosomopathy.

Abstract
Objective: The aim of the present study is to explore the clinical and genetic characteristics of 3p deletion syndrome to improve clinicians' understanding of the disease. Methods: The clinical manifestations, process of diagnosis and treatment, and genetic characteristics of an individual case of 3p deletion syndrome were analyzed. CNKI, Wanfang Data, and the Biomedical Literature Database (PubMed) were searched. The search time limit, using "3p deletion syndrome" and "BRPF1" as keywords, was from the creation of the database up to June 2020. Related data were reviewed. Results: The proband was a male child with general developmental and intellectual disabilities, special facial features and congenital heart disease. The child was the parents' first pregnancy and first born. Gene microarray analysis showed a 10.095 Mb deletion in the 3p26.3-p25.3 region, resulting in a heterozygous mutation of the BRPF1 gene; thus, the patient was diagnosed with 3p deletion syndrome. At the time of diagnosis, the child was 1 year of age and was responding to comprehensive rehabilitation training. A total of 29 well-documented cases were found in the literature, of which 19 cases had an onset within 1 year of birth, and mainly manifested with mental and motor development disabilities and abnormal facial features, with different gene deletions, depending on the size and location of the 3p deletion. Conclusion: The genetic test results of the child in this study indicated a heterozygous deletion of the BRPF1 gene on the short arm of chromosome 3, which was a unique feature of this study, since it was rarely mentioned in other reports of 3p deletion syndrome. The clinical phenotype of this syndrome is complex as it can include intellectual and motor development backwardness, low muscle tone, certain abnormal facial features (low hairline, bilateral ptosis, widely spaced eyes, a forward nose, left ear auricle deformity, a high-arched palate, a small jaw), and the deformation of systems such as the gastrointestinal tract and the urinary tract malformation or symptoms of epilepsy. As clinical manifestations can be relatively mild, the syndrome is easy to miss or misdiagnose. Clinical workers need to be aware of this disease when they find that children have special features, such as stunted growth, low muscle tone or ptosis, and it needs to be diagnosed through genetic testing. Most children are able to develop certain social skills after rehabilitation treatment.

Mol Med Rep 2017; 16:6222-6227. [PMID: 28901405 DOI: 10.3892/mmr.2017.7390] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2016] [Accepted: 07/17/2017] [Indexed: 11/06/2022] Open
Abstract
Translocations are the most frequent structural aberration in the human genome. Carriers of balanced chromosome rearrangement exhibit an increased risk of abortion and/or a chromosomally‑unbalanced child. The present study reported a clinical and cytogenetic analysis of a child who exhibited typical trisomy 4p and monosomy 20q features, including intellectual disability, delayed speech, tall stature, seizures and facial dysmorphism. The karyotype of the proband exhibited 46, XY, add(20) (q13.3). The karyotype of the mother indicated a balanced translocation karyotype: 46, XX, t(4;20) (p15.2;q13.1). The array‑based comparative genomic hybridization (aCGH) analysis identified partial trisomy of the short arm of chromosome 4 and partial monosomy of distal 20q in the proband due to maternal balanced reciprocal translocation 4;20. The analysis of genotype/phenotype correlation demonstrated that fibroblast growth factor receptor 3 and msh homeobox 1 may be the important genes for 4p duplication, and that potassium voltage‑gated channel subfamily Q member 2, myelin transcription factor 1 and cholinergic receptor nicotinic α4 subunit may be the important genes for 20q deletion. To the best of our knowledge, the present study was the first to report an unbalanced translocation involving chromosomes 4p and 20q. The present study additionally demonstrated that aCGH analysis is able to reliably detect unbalanced submicroscopic chromosomal aberrations.

Abstract
Wolf-Hirschhorn syndrome (WHS) is a multiple congenital anomaly-intellectual disability syndrome caused by a deletion involving chromosome 4p16.3. We report clinical and genetic findings of the first WHS patient diagnosed in central Africa. This boy who presented with cleft palate, microcephaly, severe growth delay, and intellectual disability was 12 years old. Typical craniofacial features were present, though the characteristic "Greek helmet" appearance of the nose was less evident, probably reflecting a variable expression related to the genetic background. The clinical diagnosis of WHS was confirmed by array CGH, which revealed a terminal 4p16.3 deletion of 3.47 Mb, typically associated with a milder phenotype, contributing to the long survival of this child in a developing country.
