The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 1q deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person. monosomy 1q partial deletion of the long arm of chromosome 1 UMLS:C5679674 partial monosomy of the long arm of chromosome 1 Orphanet:262001 icd11.foundation:296620919 1q deletion partial monosomy 1q partial deletion of the long arm of chromosome type 1 MONDO:0022756 MEDGEN:1825942
