Genes affected

ADSS1 (HGNC:20093): (adenylosuccinate synthase 1) This gene encodes a member of the adenylosuccinate synthase family of proteins. The encoded muscle-specific enzyme plays a role in the purine nucleotide cycle by catalyzing the first step in the conversion of inosine monophosphate (IMP) to adenosine monophosphate (AMP). Mutations in this gene may cause adolescent onset distal myopathy. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

The c.129C>G (p.D43E) alteration is located in exon 1 (coding exon 1) of the ADSSL1 gene. This alteration results from a C to G substitution at nucleotide position 129, causing the aspartic acid (D) at amino acid position 43 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
