摘要: Coexistence of different hereditary diseases is a known phenomenon in populations with high consanguinity rate. The resulting clinical phenotypes are extremely challenging for physicians involved the care these patients. Here we describe 6-year-old boy co-occurrence homozygous splice defect OSTM1, causing infantile malignant osteopetrosis, and loss-of-function variant MANEAL, which has not been associated human disease so far. child suffered from severe infantile-onset neurodegeneration that could be stopped by bone marrow transplantation. Magnetic resonance imaging demonstrated global brain atrophy showed hypointensities globus pallidus, corpora mamillaria, cerebral peduncles, were comparable to findings iron accumulation disorders. LC-MS/MS analysis urine cerebrospinal fluid samples revealed distinct metabolic profile mannose tetrasaccharide molecules, suggestive an oligosaccharide storage disease. Our results demonstrate exome sequencing very effective tool dissecting complex neurological diseases. Moreover, suggest MANEAL interesting candidate gene should considered context disorders and/or indications
