1q32

1q32 refers to a cytogenetic band on the long arm of chromosome 1, as observed in conventional chromosome staining. In human karyotypes this region is subdivided into 1q32.1, 1q32.2 and 1q32.3.

It lies distal to 1q31 and proximal to 1q33; exact base coordinates vary by genome assembly. The interval contains several genes; the precise gene content depends on the subband and the genome annotation version.

Abnormal copy number changes in 1q32—deletions or duplications—have been reported in the scientific literature, especially in cancers and congenital conditions; however, the clinical impact depends on the exact breakpoints and copy number.

In cytogenetics, 1q32 is used in reporting chromosomal abnormalities and is defined by banding patterns rather than fixed base-pair positions. The region’s interpretation relies on the context of neighboring bands and the overall chromosomal architecture.
