A novel variant in the GNE gene in a Malian patient presenting with distal myopathy.
GNE-myopathy (GNE-M) is a rare autosomal recessive disorder caused by variants in the GNE gene. We report a novel variant in GNE causing GNE-M in a Malian family. A 19-year-old male patient from consanguineous marriage was seen for progressive walking difficulty. Neurological examination found predominant distal muscle weakness and atrophy, decreased tendon reflexes, predominating in lower limbs. Electroneuromyography showed an axonal neuropathy pattern. However, whole exome sequencing (WES) revealed a novel biallelic variant in GNE c.1838G > A:p.Gly613Glu, segregating with the phenotype within the family. This study highlights its diagnosis challenges in sub-Saharan Africa and broadens the genetic spectrum of this rare disease.
期刊介绍：
Neurogenetics publishes findings that contribute to a better understanding of the genetic basis of normal and abnormal function of the nervous system. Neurogenetic disorders are the main focus of the journal. Neurogenetics therefore includes findings in humans and other organisms that help understand neurological disease mechanisms and publishes papers from many different fields such as biophysics, cell biology, human genetics, neuroanatomy, neurochemistry, neurology, neuropathology, neurosurgery and psychiatry.
All papers submitted to Neurogenetics should be of sufficient immediate importance to justify urgent publication. They should present new scientific results. Data merely confirming previously published findings are not acceptable.
