Pride and protein

Area of Science:

• Medical genetics
• Literary analysis
• Population genetics

Background:

• Jane Austen's "Pride and Prejudice" features a Bennet family with under-represented males and a high proportion of "silly" females.
• The study aims to identify a potential medical explanation for these observed family characteristics.

Purpose of the Study:

• To investigate a possible genetic diagnosis for the demographic and behavioral traits observed in the Bennet family.
• To analyze the representation of males and females and categorize behavioral phenotypes within the fictional family.

Main Methods:

• Retrospective literature review of "Pride and Prejudice."
• Construction of a Bennet family tree and analysis of associated phenotypes.
• Binomial modeling to assess the statistical significance of male under-representation.

Main Results:

• A statistically significant paucity of males was observed in the Bennet family (P=0.03).
• Approximately 50% of female family members exhibit "silly" behavior, which is more pronounced during social gatherings.

Conclusions:

• The findings suggest an X-linked genetic disorder, potentially fatal in males in utero or early life, explaining the low male count.
• Cognitive difficulties in female carriers may account for the 50-50 sensible/silly distribution, with social events potentially exacerbating symptoms.
• Ornithine transcarbamylase deficiency is proposed as a possible candidate disorder, though genetic testing on fictional characters is impossible; genetic counseling is recommended for carriers.
