Mutation in PYCR2 gene and hypomyelinating leukodystrophy in children: a case report study.

UNLABELLED

Hypomyelinating leukodystrophies are a heterogeneous group of inherited white matter disorders characterized by a predominant absence of myelin deposits in the central nervous system.

CASE PRESENTATION

The patient was a one-year-old girl child. She at the age of 6 months was hospitalized due to loose, muscle weakness, and an upward gaze for 7-8 min with complaints of fever and convulsions.

CLINICAL DISCUSSION

Using the test of whole exome sequencing, a nonsense homozygous mutation was found in the PYCR2 gene, which a mutation in the PYCR2 gene causes hypomyelinating leukodystrophy type 10 disease.

CONCLUSION

Advances in the field of genetics, increased awareness, and the increasing availability of genetic testing in small cities in developing countries are helping to better assess complex neurological disorders and establish a complete diagnosis.
