On this page, you will find information about a genetic change that was identified in a UDN participant. 

Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.

Changes in this gene were identified in a male, age 34 with distal myopathy 5 (OMIM 617030) (read full description).

Date of Report

Feb 18, 2020

Full Name

adenylosuccinate synthase 1

Chromosome 14 (14q32.33)


ADSSL1 encodes a member of the adenylosuccinate synthase family of proteins (Lipps & Krauss, 1999). The encoded muscle-specific enzyme plays a role in the purine metabolism pathway. Mutations in this gene may cause adolescent onset distal myopathy (Park et al., 2017).
