These marker chromosomes cannot be properly identified by conventional banding techniques alone, and molecular cytogenetic methods are necessary for a detailed characterization. Analphoid SMC derived from chromosome 7 are extremely rare, with only five cases reported so far.eng7q duplicationAnalphoid supernumerary marker chromosomeChromosome 7Partial 7q tetrasomyCase ReportHDE GENjournal article10.1186/s13039-016-0295-z
