A rare metabolic disorder the Inuit have is called carnitine palmitoyltransferase 1A ( CPT1A ) deficiency .
And earlier studies showed that the Inuit have a very high frequency�68 % to 81 % in certain arctic coastal populations�of an extremely rare autosomal recessive mutation of the CPT1A gene�a key regulator of mitochondrial long-chain fatty-acid oxidation�which results in a rare metabolic disorder known as carnitine palmitoyltransferase 1A ( CPT1A ) deficiency and promotes hypoketotic hypoglycemia�low levels of ketones and low blood sugar .
