The present, yet preliminary, observation that renal and temporal bone malformations are less frequent in SIX1-related disease suggests a slightly different clinical profile compared to EYA1-related disease.

The SALL1 gene has been associated with the Townes-Brocks Syndrome (TBS), a disorder characterized by multiorgan dysgenesis including renal and genital malformations.
Using temporally and spatially controlled genetic manipulations, this study provides the first <i>in vivo</i> report that autonomous FMRP regulates multiple stages of dendritic development, and that selective reduction of postsynaptic FMRP leads to abnormal development of excitatory presynaptic terminals and compromised neurotransmission.
We analysed 3D facial photographs of 51 males and 15 females with full FMR1 mutations and 9 females with a premutation using dense-surface modelling techniques and a new technique that forms a directed graph with normalized face shapes as nodes and edges linking those with closest dysmorphism.
Targeted deletion of Dll3 in the mouse causes a developmental defect in somite segmentation, and consequently vertebral formation is severely disrupted, closely resembling human SCD.
To aid in elucidation of the underlying developmental defect in SCDO1, we have generated a mouse model by targeted deletion of the Dll3 gene (Dunwoodie et al., 2002).
The objective of this study was to compare the expression of Folate Receptor-α (FR-α), Reduced Folate Carrier (RFC), and Proton Coupled Folate Transporter (PCFT) in placentas from pregnancies complicated with birth defects (BD) and controls.
Suppression of Folr1 expression in the nascent cardiac NC by site-directed short-interfering RNA (siRNA) altered cardiac NC cell mitosis and subsequent migration patterns leading to abnormal development of the pharyngeal arch arteries (PAA) and outflow tract. qPCR analysis demonstrated that the siRNA treatment significantly reduced Folr1 24 hr after treatment.
Taken together, the data identify a new protein essential for notochord morphogenesis, extend our understanding of gene-nutrient interactions in early development, and suggest that human mutations in COL8A1 may cause structural birth defects.
In cases of d-TGA, the FINE method has a high success rate in generating 3 specific abnormal cardiac views and therefore can be performed to screen for this congenital defect.
The case with bilateral renal agenesis presented a novel combination of a null allele and a putative C-terminus missense mutation in the DHCR7 gene CONCLUSIONS: In view of the discrepancy between the prevalence of SLOS among newborns and the carrier frequency of a heterozygous DHCR7 gene mutation, the syndrome-specific internal malformation pattern may be helpful not to miss SLOS diagnosis in fetuses at prenatal ultrasound and fetal autopsy.
The most frequent a-CGH abnormalities were detected in cases of congenital heart diseases (CDHs), multiple malformations and central nervous system (CNS) malformations.
The GREM1 is involved in the etiology of NSCL±P in the Brazilian population and reveal that the interaction between GREM1 and NTN1 may be related with the pathogenesis of this common craniofacial malformation.
