Key result
Familial occurrence of mitral valve prolapse was 26.8% overall and did not depend on its association with straight back syndrome (20% prevalence) compared to those without (38.5%).
Why the study?
Is the familial occurrence of mitral valve prolapse related to the straight back syndrome?

Is the familial occurrence of mitral valve prolapse related to the straight back syndrome?
Familial mitral valve prolapse screening in relatives may proceed irrespective of straight back syndrome; leaves open independent transmission in Chinese cohorts.
Familial prevalence of mitral valve prolapse in a Chinese population was determined in 22 propositi of whom 10 had straight back (group A), three had abnormally high metacarpal index (group B), and nine had neither (group C). Of 71 (32 male and 39 female subjects) first degree relatives screened, mitral valve prolapse was found in 19 (seven male and 12 female subjects) (26.8%). The familial prevalence among groups A, B, and C was 20%, 30%, and 38.5%, respectively. Our study indicates that the familial occurrence of mitral valve prolapse does not depend on its association with the straight back syndrome.

Chen et al. (1983) conducted a cross-sectional in Mitral valve prolapse (n=71). Straight back syndrome vs. Neither straight back syndrome nor abnormally high metacarpal index was evaluated on Familial prevalence of mitral valve prolapse. Familial occurrence of mitral valve prolapse was 26.8% overall and did not depend on its association with straight back syndrome (20% prevalence) compared to those without (38.5%).
