Аннотация
BACKGROUND: Glutaric acidemia (GAI) and mucopolysaccharidosis type IIIB (MPSIIIB) are two rare genetic disorders caused by pathogenic variants in two different genes. Here, we report a coexistence of these two different rare disorders in an individual.
METHODS: A four-year-old Iranian boy born to first-cousin parents suspected to have MPSIIIB and/or GAI was investigated in this study. Targeted genomic enrichment and next-generation sequencing were used to examine genes related to MPS and GA. Sanger sequencing was performed to confirm the results.
RESULTS: Two homozygous likely pathogenic variants in α-N-acetylglucosaminidase (NAGLU) and GCDH genes were found and confirmed in the proband.
CONCLUSION: A combination of specific features of two different diseases in a patient has been reported here. More studies on this case and similar cases can provide more information about the effect of simultaneous pathogenic variants in different genes.
