OBJECTIVE: To explore the clinical features and genetic etiology of a child with glycogen storage disease VI (GSD-VI).
METHODS: Clinical data and laboratory results of the patient were collected. Whole exome sequencing (WES) was carried out for the patient. Candidate variant and its parental origin was verified by Sanger sequencing.
RESULTS: The patient was a 3-year-and-9-month old boy whom has featured abdominal distention, hepatomegaly, short stature and elevated hepatic transaminase. WES revealed the he has harbored compound heterozygous variants of the PYGL gene, namely c.697G>A (p.Gly233Ser) and c.320dupA (p.Asn107fs). Sanger sequencing has verified that the two variants have derived from his father and mother, respectively. The c.320dupA (p.Asn107fs) variant was unreported previously.
CONCLUSION: The compound heterozygous variants of the PYGL gene probably underlay the GSD-VI in this patient. Above finding has enriched the spectrum of PYGL gene variants and provided a basis for the treatment and genetic counseling.
