A consecutive sample of 836 individuals were recruited between April and October of 2019 (303 born with cleft lip and palate, 256 relatives mostly of the maternal side of individuals born with cleft lip and palate, and 277 unaffected unrelated individuals). Parents or guardians of the children answered a questionnaire with basic demographic information about their children and their family history of cleft lip and palate and cancer. DNA was obtained from whole saliva and IRE1 rs196929 was genotyped using TaqMan chemistry and end-point analysis. Over-representation of alleles was determined using chi-square as implemented in PLINK using an alpha of 0.05. There was an excess of less common homozygotes of IRE1 rs196929 among relatives of individuals born with cleft lip and palate when they had positive family history of cancer in comparison with individuals born with cleft lip and palate or with unrelated unaffected individuals (P = 0.0006 and P  less then  0.001, respectively). This pattern was similar when families reported one type of cancer or multiple ones, or when cancer affecting females (breast or reproductive tract) or the structures of the gastro-intestinal tract were considered. These results provide support for a role of the ER stress IRE1-XPB1 pathway in the higher frequency of cancer in families of individuals born with cleft lip and palate.In this experimental anatomic study, the authors examined the number and distribution of muscle spindles in the levator palpebrae superioris (LPS) muscle of human adults. This study included 11 orbits from 11 cadavers (mean age at death, 81.9 years). The LPS muscles were harvested and equally divided into 5 sections using transverse incisions. Muscle spindles were counted in each section. Consequently, muscle spindles were iden
