  • Segregation analyses define the range of genetic hypotheses that can account for the observed transmission patterns. (acnp.org)
  • Initial evidence of a genetic basis for susceptibility to lung cancer came from observations of individual differences in susceptibility to the same environmental risk factors ( 1 - 3 ), familial aggregation of lung cancer after accounting for personal smoking ( 4 ), increased risk of lung cancer mortality in siblings ( 5 ), and segregation analyses ( 6 - 11 ).

  • Sanger sequence analysis of PTPN11 coding regions in a total of 17 MC families identified mutations in 10 of them (5 frameshift, 2 nonsense, and 3 splice-site mutations). (plos.org)
  • Bioinformatic analyses suggested that both mutations are deleterious for the native three-dimensional structure of the PDE6β protein. (molvis.org)
  • A cohort of 41 mostly pure HSP patients from Britain and Austria, 30 of whom displayed AD inheritance, was screened for mutations in SPG4 by single strand conformation polymorphism (SSCP) analysis followed by sequencing of samples with mobility shifts. (embl-heidelberg.de)
  • Protein and transcript analyses of patients carrying either nonsense or frameshift spastin mutations revealed neither truncated protein nor mutated transcripts, providing evidence that these mutations are responsible for a loss of spastin function. (embl-heidelberg.de)
  • I first estimated the portion of variance in brain weight due to sex, age, body weight, litter size, and parity by regression analysis. (nervenet.org)
  • A combination of risk alleles identified by genome-wide association studies led to the development of a score to predict disease severity, which could improve the management of the disease. (springer.com)
  • Alleles were assigned to individuals, which allowed calculation of LOD scores. (ugent.be)
  • Expected LOD score for 1000 nuclear families with 4 offspring, where σ 2 mg = 0.2, σ 2 pg = 0,…, 0.8, σ 2 e = 0.8 − σ 2 pg and σ 2 m = σ 2 mg + σ 2 pg + σ 2 e = 1. (nih.gov)

  • The results of 180 healthy Japanese demonstrate that the ratio containing repeat sequences, not only segmental repeats but also long interspersed nuclear element (LINE) sequences both in the start and end regions of the CNVs, is higher in CNVs that are commonly detected among multiple individuals than that in randomly selected regions, and the conservation score based on primates is lower in these regions than in randomly selected regions.
