Nonsyndromic cleft lip and/or cleft palate (NSCLP) are common congenital anomalies in humans, the etiologies of which are complex and associated with both genetic and environmental factors. Previous data suggested single nucleotide polymorphisms (SNPs) of rs1546124, rs4783099, and rs16974880 of the CRISPLD2 gene were associated with an increased risk of NSCLP; however, subsequent studies have yielded conflicting results. This study aims to evaluate the associations of the aforementioned polymorphisms with NSCLP in a Northwestern Chinese population. Three CRISPLD2 SNPs were genotyped in a case-control study (n = 907), including 444 NSCLP patients and 463 healthy individuals, using polymerase chain reaction-denaturing high-performance liquid chromatography (PCR-DHPLC). The genotype and allele frequencies of rs1546124 (odds ratio [OR], 2.30; 95% confidence interval [CI], 1.58-3.34; p = 1 × 10(-5) ) and rs4783099 (OR, 0.73; 95% CI, 0.54-1.00; p = 0.05) were different in NSCLP patients compared with controls. Furthermore, the CC genotype at rs1546124 was associated with increased risk for cleft lip with or without cleft palate (CL/P; OR, 2.11; 95% CI, 1.41-3.15; p(correct) = 1.5 × 10(-4) ) and for cleft palate only (CPO; OR, 2.93; 9...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
