Chromosome 13 and 21 markers, along with position on chromosome (ensembl.org). Alleles were assigned arbitrary numbers, and genotype information is given for the patient and parents. Inheritance patterns have been determined. P indicates paternal inheritance and M indicates maternal inheritance. Bolded inheritance patterns demonstrate the expression of a single paternal allele and no maternal alleles in the patient, when the father is heterozygous.
