Abstract
The 4q deletion syndrome is an uncommon condition manifesting with broad clinical expression and phenotypic variability. We report a 5-year-old boy affected by 4q deletion syndrome who showed minor craniofacial features, growth failure, mild developmental delay, severe speech delay, and marked irascibility and aggressivity. Moreover, he showed precocious and crowded primary dentition, digital hyperlaxity, and congenital bilateral adducted thumbs, signs which were previously unreported in the syndrome. The array comparative genomic hybridization analysis revealed a 4q partial terminal deletion of ∼329.6 kb extending from 164.703.186 to 165.032.803 nt, which includes part of MARCH1 (membrane associated ring-CH-type finger 1) gene (OMIM#613331). Same rearrangement was found in his healthy mother. Clinical phenotype of the child and its relationship to the deleted region is presented with a revision of the cases having the same copy number losses from the literature and genomic variant databases.

Abstract
A 21-week-old still born female fetus with occipital encepholocele, cleft lip and cleft palate was received from the Department of Obstetrics and Gynecology, Mahatma Gandhi Medical College and Research Institute, Pondicherry and was studied in detail. It was born to Primigravida, of a second degree consanguineous marriage, with unremarkable family history. The biometric measurements were noted which corresponded to the age of the fetus. Further the fetus was embalmed and dissected. On examination an encephalocele of 2.7×1.5 cm was seen in the occipital region with a midline defect in the occipital bone and herniated brain tissue. Other anomalies observed were right unilateral cleft lip, right cleft palate, and bilateral syndactyly of the lower limbs and associated Congenital Talipus Equino Varus of the right foot. Other internal organs were developed appropriate for the age of the fetus.

Abstract
BACKGROUND Terminal deletions of chromosome 4q are associated with a broad spectrum of phenotypes including cardiac, craniofacial, digital, and cognitive impairment. The rarity of this syndrome renders genotype-phenotype correlation difficult, which is further complicated by the widely different phenotypes observed in patients sharing similar deletion intervals. CASE PRESENTATION Herein, we describe a boy with congenital hearing impairment and a variety of moderate syndromic features that prompted SNP array analysis disclosing a heterozygous 6.9 Mb deletion in the 4q35.1q35.2 region, which emerged de novo in the maternal germ line. CONCLUSION In addition to the index patient, we review 35 cases from the literature and DECIPHER database to attempt genotype-phenotype correlations for a syndrome with great phenotypic variability. We delineate intervals with recurrent phenotypic overlap, particularly for cleft palate, congenital heart defect, intellectual disability, and autism spectrum disorder. Broad phenotypic presentation of the terminal 4q deletion syndrome is consistent with incomplete penetrance of the individual symptoms.

Abstract
Chromosome inversions are intra-chromosomal rearrangements formed when the chromosome breaks occur at two places, and in the process of repair the intervening segments are joined in an inverted or opposite manner. Inversions themselves do not appear to cause clinical anomalies, if balanced. Abnormal phenotypes can occur due to gene disruption at the point of breakage and reunion or due to duplication/deficiency recombinants formed during crossover at meiosis. We report a case with familial deletion 4q syndrome in a 1-year-old female child with dysmorphism and congenital abnormalities. The deletion was an outcome of a paracentric inversion 4q31.2q35.2. The deletion was confirmed by fluorescence in situ hybridization using telomeric DNA probes for chromosome No. 4. An attempt was made to correlate the genotype with the phenotype. The father had the same rearrangement with a milder phenotype. The recurrence risk in such cases is high.

Abstract
Chromosome 4q deletion syndrome (4q- syndrome) is a rare condition, with an estimated incidence of 1 in 100,000. Although variable, the clinical spectrum commonly includes craniofacial, developmental, digital, skeletal, and cardiac involvement. Data on the genotype-phenotype correlation within the 4q arm are limited. We present detailed clinical and genetic information by array CGH on 20 patients with 4q deletions. We identified a patient who has a ∼465 kb deletion (186,770,069-187,234,800, hg18 coordinates) in 4q35.1 with all clinical features for 4q deletion syndrome except for developmental delay, suggesting that this is a critical region for this condition and a specific gene responsible for orofacial clefts and congenital heart defects resides in this region. Since the patients with terminal deletions all had cleft palate, our results provide further evidence that a gene associated with clefts is located on the terminal segment of 4q. By comparing and contrasting our patients' genetic information and clinical features, we found significant genotype-phenotype correlations at a single gene level linking specific phenotypes to individual genes. Based on these data, we constructed a hypothetical partial phenotype-genotype map for chromosome 4q which includes BMP3, SEC31A, MAPK10, SPARCL1, DMP1, IBSP, PKD2, GRID2, PITX2, NEUROG2, ANK2, FGF2, HAND2, and DUX4 genes.

Abstract
The 2q3 duplication and 4q3 deletion syndromes are two conditions with variable phenotypes including Pierre-Robin sequence (PRS), limb anomalies, congenital heart defects (CHD), developmental delays and intellectual disabilities. We describe a patient born to a mother with a balanced t(2; 4) translocation who combines both a 2q34-qter duplication and a 4q34.2-qter deletion through inheritance of the derivative chromosome 4 (der(4)). He showed developmental delay, growth retardation, hearing problems, minor facial and non-facial anomalies, such as bilateral fifth finger shortness and clinodactyly, but no PRS or CHD. The comparison of his features with those of 46 and 65 published cases of 2q3 duplication and 4q3 deletion, respectively, allows us to further restrict the size of the proposed critical intervals for PRS and CHD on chromosome 4.

Abstract
Variable clinical presentations of patients with chromosomally detected deletions in the distal long arm (q) of chromosome 4 have been reported. The lack of molecular characterization of the deletion sizes and deleted genes hinders further genotype-phenotype correlation. Using a validated oligonucleotide array comparative genomic hybridization (oaCGH) analysis, we examined two patients with apparent chromosomal deletions in the distal 4q region. In the first, oaCGH identified a 2.441 megabase (Mb) duplication and a 12.651 Mb deletion at 4q34.1 in a pregnant female who transmitted this aberration to her son. This mother has only learning disabilities while her son had both renal and cardiac anomalies in the newborn period. Unrecognized paternal genetic factors may contribute to the variable expression. The second patient is a 17-year-old female with a history of Pierre Robin sequence, cardiac abnormalities and learning disabilities. She was diagnosed prenatally with a de novo 4q deletion, and oaCGH defined a 16.435 Mb deletion of 4q34.1-4q35.2. Phenotypic comparison and subtractive genomic mapping between these two cases suggested a 4 Mb region possibly harboring a candidate gene for Pierre Robin sequence. Our cases and review of reported cases with genomic findings indicated the presence of familial variants with variable expressivity as well as de novo or inherited pathogenic simple deletion, duplication and complex deletion and duplication in the distal 4q region.

Abstract
Fetuses with neural tube defects (NTDs) carry a risk of chromosomal abnormalities. The risk varies with maternal age, gestational age at diagnosis, association with other structural abnormalities, and family history of chromosome aberrations. This article provides a comprehensive review of structural chromosomal abnormalities associated with NTDs, such as del(13q), r(13), dup(2p), del(2q), del(1p), del(1q), dup(1q), del(3p), dup(3p), del(3q), dup(3q), del(4p), dup(4p), del(4q), dup(4q), del(5p), del(6p), dup(6q), del(6q), dup(7p), del(7q), dup(8q), del(9p), del(10q), del(11q), dup(11q), dup(12p), dup(14q), del(14q), del(15q), dup(16q), del(18q), r(18), dup(20p), +i(20p), del(22q), del(Xp), and dup(Xq). NTDs may be associated with aneuploidy. Perinatal identification of NTDs should alert one to the possibility of chromosomal abnormalities and prompt a thorough cytogenetic investigation and genetic counseling.
