In particular, human haemochromatosis protein (HFE) is involved in iron metabolism, and HFE H63D polymorphism has been related to the risk of amyotrophic lateral sclerosis and Alzheimer's disease.

These results suggest okra may be beneficial in people expressing the H63D variant to reduce the risk of AD and other neurodegenerative diseases related to oxidative stress.

In AtAD, HFE SNP rs1799945 was the strongest predictor of disease; variation in HFE has previously been implicated in AD risk in non-ε4 carriers.

These results indicate that the alterations in cholesterol metabolism associated with expression of H63D-HFE may contribute to the development of AD.

Factors included: apolipoprotein E (ApoE) gene variants (the E4 allele is the strongest confirmed genetic predisposing factor for Alzheimer's disease), the hemochromatosis-HFE gene mutations (H63D and C282Y), diabetes, and stroke.

A specific polymorphism in the hemochromatosis (HFE) gene, H63D, is over-represented in neurodegenerative disorders such as amyotrophic lateral sclerosis and Alzheimer disease.

These changes may explain why C282Y-HFE is a risk factor for colon and breast cancer and possibly protective against Alzheimer's disease while H63D-HFE is a risk factor for neurodegenerative diseases.

These findings support our hypothesis that the presence of the HFE H63D allele enables factors that trigger neurodegenerative processes associated with AD and predisposes cells to cytotoxcity.

Previous studies in cell models have shown the H63D HFE variant to result in increased cellular iron, oxidative stress, glutamate dyshomeostasis, and an increase in tau phosphorylation; all processes thought to contribute to AD pathology.

Here we tested the potential association of CAT53 with the risk of developing AD and searched for potential haplotypic associations of CAT53 with two common mutations (H63D, C282Y) in the HFE gene, also located at chromosome 6p21.3.

In addition, in APOE epsilon 4 carriers, the mean age at onset of AD was earlier in men homozygous for the H63D variant (73.2+/-2.1 versus 78.7+/-1.6, p=0.05).

The frequency of H63D mutation was higher in control population (29.9%) than in AD patients (18%), suggesting a protective role of this allele on AD either due to the presence of the mutation itself or through the effect of other related genes in the ancestral haplotype in which it is included.

We observed no significant impact of H63D or C282Y heterozygosity on age at AD symptoms onset or diagnosis, age at onset of cognitive symptoms (AD and MCI combined), rates of MCI-to-AD conversion or specific neuropsychological deficits.

Our data show that the mutant H63D allele potentially interacts with the ApoE epsilon4 allele to significantly reduce age at onset of AD compared to ApoE epsilon4 carriers alone, but has no effect on age at onset in ApoE epsilon4 non-carriers.
