LongevityMap Gene

Gene details

HGNC symbol: HFE
Aliases: HH; HFE1; HLA-H; MVCD7; TFQTL2
Common name: hemochromatosis
Description: The protein encoded by this gene is a membrane protein that is similar to MHC class I-type proteins and associates with beta2-microglobulin (beta2M). It is thought that this protein functions to regulate iron absorption by regulating the interaction of the transferrin receptor with transferrin. The iron storage disorder, hereditary haemochromatosis, is a recessive genetic disorder that results from defects in this gene. At least nine alternatively spliced variants have been described for this gene. Additional variants have been found but their full-length nature has not been determined.

Study 1

Longevity Association

Population

Italian (Sicily)

Study Design

C282Y, H63D and S65C polymorphisms were studied in 106 young controls (age range from 22 to 55 years; 40 men and 66 women) and 35 elderly subjects (age range from 91 to 105 years; seven men and 28 women)

Conclusions

A significant difference was observed only in women in frequencies of C282Y alleles between the young and the elderly subjects. Concerning H63D polymorphisms, no significant differences were observed, between old and young people.

Study 2

Longevity Association

Population

Italian (Sicily)

Study Design

C282Y, H63D and S65C polymorphisms were studied in 106 young controls (22 - 55 years; 40 men) and 35 elderly subjects (91 - 105 years; 7 men)

Conclusions

A significant difference (P = 7.2 × 10−7 by Fisher exact test) was observed only in women in frequencies of C282Y alleles between the young and the elderly subjects. Concerning H63D polymorphisms, no significant differences were observed, between old and young people.

Study 3

Longevity Association

Non-significant

Population

Italian (Sardinia)

Study Design

The C282Y, H63D and S65C SNPs were examined in 61 controls and 57 centenarians

Conclusions

Although there was a trend for an increased frequency of the H63D allele in centenarian women, no significant differences were observed in frequencies of the different alleles between young and centenarians

Study 4

Longevity Association: Non-significant
Population: Danish, German, Dutch
Study Design: 102 SNPs from 16 longevity candidate genes were examined in Danish. 1089 individuals (ages 92.2-93.8, mean age 93.2, 71.3 female) and 736 middle-aged controls (46-55 y, mean age 50.6, 49.6% female) were involved in this case-control study. Then the results were replicated in a German cohort of 1613 individuals (95-110 y, 73.2% female) and 1104 middle-aged controls (mean age 67.2, SD 4.07, 74.3% female). A 11 years study was introduced in Danish cohort to identify the SNPs associated with longevity, then the results were verified in Dutch longitudinal cohort.
Conclusions: After correcting for multiple testing, no SNPs were significantly associated with longevity, except in APOE and CETP. rs4343 (ACE) was nominally significantly associated with longevity (P < 0.05).

Study 5

Longevity Association

Non-significant

Population

Italian (Sicily)

Study Design

C282Y, H63D and S65C polymorphisms were studied in 106 young controls (22 - 55 years; 40 men) and 35 elderly subjects (91 - 105 years; 7 men)

Conclusions

Concerning H63D polymorphisms, no significant differences were observed, between old and young people. S65C was not detected.
