Abstract Objective: To explore the clinical features and mutations of the TRPM6 gene in an infant featuring hypomagnesemia and secondary hypocalcemia.
Methods: Clinical data of the patient was collected. Genomic DNA was extracted from peripheral blood samples from the patient and her parents. Targeted exome sequencing was carried out to screen the potential mutations. Suspected mutations were verified by Sanger sequencing.
Results: A novel homozygous c.5538delA (p.Q1846Qfs*2) mutation in the TRPM6 gene was identified in the proband, for which both of her parents were heterozygous carriers.
Conclusion: The homozygous frameshift mutation of TRPM6 gene (c.5538delA) probably underlies the disease in the proband. The finding has expanded the mutation spectrum of TRPM6 gene.
