[[http://www.uniprot.org/uniprot/SYG_HUMAN SYG_HUMAN]] Defects in GARS are the cause of Charcot-Marie-Tooth disease type 2D (CMT2D) [MIM:[http://omim.org/entry/601472 601472]]. CMT2D is a form of Charcot-Marie-Tooth disease, the most common inherited disorder of the peripheral nervous system. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathy or CMT1, and primary peripheral axonal neuropathy or CMT2. Neuropathies of the CMT2 group are characterized by signs of axonal regeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. CMT2D is characterized by a more severe phenotype in the upper extremities (severe weakness and atrophy, absence of tendon reflexes) than in the lower limbs. CMT2D inheritance is autosomal dominant.<ref>PMID:12690580</ref> Defects in GARS are a cause of distal hereditary motor neuronopathy type 5A (HMN5A) [MIM:[http://omim.org/entry/600794 600794]]; also known as distal hereditary motor neuropathy type V (DSMAV). A disorder characterized by distal muscular atrophy mainly affecting the upper extremities, in contrast to other distal motor neuronopathies. These constitute a heterogeneous group of neuromuscular diseases caused by selective degeneration of motor neurons in the anterior horn of the spinal cord, without sensory deficit in the posterior horn. The overall clinical picture consists of a classical distal muscular atrophy syndrome in the legs without clinical sensory loss. The disease starts with weakness and wasting of distal muscles of the anterior tibial and peroneal compartments of the legs. Later on, weakness and atrophy may expand to the proximal muscles of the lower limbs and/or to the distal upper limbs.<ref>PMID:12690580</ref>

[https://www.uniprot.org/uniprot/GARS_HUMAN GARS_HUMAN] Catalyzes the ATP-dependent ligation of glycine to the 3'-end of its cognate tRNA, via the formation of an aminoacyl-adenylate intermediate (Gly-AMP) (PubMed:17544401, PubMed:28675565, PubMed:24898252). Also produces diadenosine tetraphosphate (Ap4A), a universal pleiotropic signaling molecule needed for cell regulation pathways, by direct condensation of 2 ATPs. Thereby, may play a special role in Ap4A homeostasis (PubMed:19710017).<ref>PMID:17544401</ref> <ref>PMID:19710017</ref> <ref>PMID:24898252</ref> <ref>PMID:28675565</ref>
