The signs in IOSCA demonstrate a fairly distinct pattern. Among these, peripheral neuropathy seems to be the most common presenting feature in C10orf2 defects.engTwinkleDoenças GenéticasIdentification of maternal uniparental isodisomy of chromosome 10 in a patient with mitochondrial DNA depletion syndromeconference object
