On this page, you will find information about a genetic change that was identified in a UDN participant. We are trying to find others with the same or similar condition.
Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.
A change in the HLCS gene was identified in a UDN participant with decline in language and memory (cognitive regression), sudden muscle jerks (myoclonus), and increased muscle tone in lower limbs (limb hypertonia)

The HLCS gene links biotin to propionyl-CoA carboxylase, pyruvate carboxylase, alpha-methylcrotonyl-CoA carboxylase and acetyl-CoA carboxylase (Suzuki et al., 1994).
A heterozygous change in this gene was identified in a UDN participant. Research is underway to see if this change is causing symptoms in this participant.
