Human HDLBP peptide

Objective: We present prenatal diagnosis of terminal 2q deletion and distal 10q duplication of paternal origin in a fetus associated with increased nuchal translucency and abnormal maternal serum screening results. Case report: A 26-year-old woman who had experienced spontaneous abortion twice underwent amniocentesis at 16 weeks of gestation because of an increased nuchal translucency thickness of 3.5 mm at 12 weeks of gestation and abnormal maternal serum screening results of 2.573 multiples of the median (MoM) of free beta-human chorionic gonadotrophin (beta-hCG) and 1.536 MoM of pregnancy-associated plasma protein-A (PAPP-A) resulting in a trisomy 21 risk of 1:64. Amniocentesis revealed a derivative chromosome 2. Simultaneous array comparative genomic hybridization (aCGH) analysis on the DNA extracted from uncultured amniocytes revealed arr [hg19] 2q37.3 (238,294,223-242,782,258) x 1, 10q24.31q26.3 (102,018,246-135,426,386) x 3. Cytogenetic analysis of parental bloods revealed a karyotype of 46,XX in the mother and a karyotype of 46,XY,t(2;10)(q37.3;q24.3) in the father. The fetal karyotype was 46,XX,der(2)t(2;10)(q37.3;q24.3)pat. The pregnancy was terminated at 20 weeks of gestation, and a malformed fetus was delivered with facial dysmorphism. Postnatal analysis of the cord blood confirmed the results of prenatal diagnosis. The fetus had a 4.693-Mb deletion of 2q37.3 encompassing the genes of HDAC4, KIF1A, PASK, HDLBP, FARP2 and D2HGDH, and a 33.34-Mb duplication of 10q24.31-q26.3 encompassing the gene of NF kappa B2. Conclusion: First-trimester ultrasound and maternal serum biochemistry screening may help to identify an unexpected unbalanced familial translocation at prenatal diagnosis.

A recent association scan using a genome-wide set of nonsynonymous coding single-nucleotide polymorphisms (nsSNPs) conducted in four diseases including Graves' disease (GD), identified nine novel possible regions of association with GD. We used a case-control approach in an attempt to replicate association of these nine regions in an independent collection of 1578 British GD patients and 1946 matched Caucasian controls. Although none of these loci showed evidence of association with GD in the independent data set, when combined with the original Wellcome Trust Case-Control Consortium study group, minor differences in allele frequencies (P >= 10(-3)) remained in the combined collection of 5924 subjects for four of the nsSNPs, present within HDLBP, TEKT1, JSRP1 and UTX. An additional 29 Tag SNPs were screened within these four gene regions to determine if further associations could be detected. Similarly, minor differences only (P = 0.042-0.002) were detected in two HDLBP and two TEKT1 Tag SNPs in the combined UK GD collection. In conclusion, it is unlikely that the SNPs selected in this replication study have a significant effect on the risk of GD in the United Kingdom. Our study confirms the need for large data sets and stringent analysis criteria when searching for susceptibility loci in common diseases.
