Objectives

Narrative objectives1

We will search for statistically significant associations between subjective symptoms of cold hypersensitivity and genetic factors. In addition, we will compare the obtained data and interpret the results biologically to analogize the physiological mechanism of cold hypersensitivity.

Basic objectives2

Others

Basic objectives -Others

Although it has been suggested that cold hypersensitivity may be caused by genetic background, there are few reports on genetic analysis related to cold hypersensitivity, and the influence of genetic factors on cold hypersensitivity is not clear. In this study, we conduct a questionnaire survey of adult female volunteers (aged between 20 and 60 years) who had received the MYCODE genetic testing service (hereafter referred to as MYCODE) conducted by DeNA Life Sciences, Inc. We will explore the association between subjective symptoms of cold hypersensitivity and genetic polymorphism centered on SNPs (Single Nucleotide Polymorphism).

Key exclusion criteria

1. Those who are currently diagnosed with heart failure, abnormal thyroid function (hyperthyroidism, hypothyroidism, chronic thyroiditis, or Hashimoto's disease), or malignancy (to potentially affect the evaluation)
2. Those who are currently hospitalized (as this may affect the evaluation)
3. Those who are currently pregnant or may become pregnant (as this may affect the evaluation).
4. Those who are judged to be excluded by the researcher (because it may affect the evaluation)

Number of participants that the trial has enrolled

1200

Results

Among the 1111 participants, 599 reported cold hypersensitivity. Higher cold hypersensitivity severity was positively associated with the SSS-8 scores. A GWAS for cold hypersensitivity was conducted using array-based genomic data obtained from genetic testing. We identified 11 lead variants showing suggestive associations (P < 0.00001) with cold hypersensitivity, some of which showed a reasonable change in expression in specific tissues in the GTEx database.

Baseline Characteristics

1200 Japanese adult female volunteers (age: 20 to 59 years), recruited between April 21 and May 25, 2022, who were customers of MYCODE, a personal genome service in Japan.

Participant flow

A total of 1200 subjects were enrolled in the study, of whom 1111 met the inclusion criteria.

Adverse events

None

Outcome measures

Among the 1111 participants, 599 (54%) reported cold hypersensitivity. Higher cold hypersensitivity severity was positively associated with the SSS-8 scores. Additionally, a genome-wide association study for cold hypersensitivity was conducted using array-based genomic data obtained from genetic testing. We identified 11 lead variants showing suggestive associations (P < 0.00001 ) with cold hypersensitivity, some of which showed a reasonable change in expression in specific tissues in the Genotype-Tissue Expression database.

Other related information

The MYCODE customers who have given comprehensive research consent to have their genetic/health-related data used for research purposes are invited to participate in this study by an email informing its overview. Participants who provide online consent for participation are asked to answer an online questionnaire including information on attributes such as age, height, weight, current medical history, and symptoms of cold hypersensitivity. The answer data as well as genetic data already obtained by MYCODE will be anonymized and then used to analyze the relationship between genetic polymorphism and cold hypersensitivity. Under the overall management of Keio University, DeNA Life Science Inc. will conduct genetic analysis and Keio University will conduct questionnaire-to-questionnaire analysis on cold hypersensitivity and burden of physical symptoms based on an assessment protocol predetermined by TSUMURA & CO.
