Summaries for Harel-Yoon Syndrome

OMIM : 57 Harel-Yoon syndrome is a syndromic neurodevelopmental disorder characterized by delayed psychomotor development, intellectual disability, truncal hypotonia, spasticity, and peripheral neuropathy. Other more variable features such as optic atrophy may also occur. Laboratory studies in some patients show evidence of mitochondrial dysfunction (summary by Harel et al., 2016). (617183)

MalaCards based summary : Harel-Yoon Syndrome, is also known as hayos. An important gene associated with Harel-Yoon Syndrome is ATAD3A (ATPase Family, AAA Domain Containing 3A). Affiliated tissues include eye, and related phenotypes are frontal bossing and nystagmus

UniProtKB/Swiss-Prot : 75 Harel-Yoon syndrome: A syndrome characterized by global developmental delay, hypotonia, intellectual disability, and axonal neuropathy. Some patients have optic atrophy and hypertrophic cardiomyopathy. HAYOS inheritance can be autosomal dominant or autosomal recessive.
