M/P, biparental inheritance; H, heterozygous (either parent not available, or inheritance of common parental allele by proband); PD, paternally-derived deletion; MD, maternally-derived deletion; D, deleted (parental origin indeterminate); I, intact (parental origin indeterminate); ni, not informative; nd, no data available. Locus order is derived from Beckmann et al. [1993], and the Genome Database.

STRP polymorphic locus.

Copy number based on calibrated gene dosage.

IGF1R has been localized to 15q26.1, but has not been assigned on the genetic linkage map.
