Alpha-mannosidosis is a lysosomal storage disorder caused by mutations in MAN2B1 gene. A 7-year-old girl child, born of a consanguineous marriage, presented with developmental delay, seizures, and hearing impairment. On examination, she had coarse features without hepatosplenomegaly. On investigations, low levels of the enzyme alpha-mannosidase level were observed. Targeted next-generation sequencing revealed a novel pathogenic variant p.Trp469Ter on exon 11 of MAN2B1 gene.
