19q134

19q134 is not a standard, widely recognized cytogenetic designation in human genetics. In conventional human karyotype notation, locations on chromosome 19 are described using the long arm (q) and a decimal-based banding system such as 19q13.4. The string 19q134 does not conform to this scheme and is likely a typographical error, a lab-specific identifier, or an internal code (for example, a clone name, probe label, or project identifier) rather than a defined chromosomal band.

Understanding the standard notation helps place 19q134 in context. Cytogenetic bands divide each chromosome into regions that are labeled with the chromosome number, arm letter (p or q), and numeric region and band numbers (for example, 19q13.4). These bands correspond to specific ranges in reference genome builds (such as GRCh38) and are used to describe the location of genes, deletions, duplications, or other rearrangements. The region 19q13.4 is a real and gene-rich area that has been studied in various genomic contexts, though exact gene content depends on the genome build and annotation source.

If a lab or paper presents the term 19q134, verification is advisable. Check the context for clues about whether it was meant to denote a standard band (likely 19q13.4), a specific clone or probe, or another identifier.Consult reputable resources such as genome browsers (UCSC, Ensembl) or cytogenetics references to confirm the intended locus and to retrieve information on nearby genes, regulatory elements, or known variants. In the absence of additional context, 19q134 should be treated as ambiguous rather than a defined chromosomal region.
