| description | This gene is maternally imprinted and only expressed when paternally inherited. Inheritance of the maternal allele in the heterozygous state is equivalent to wild-type homozygotes where as inheritance of the paternal allele in the heterogyzous state is equivalent to knock-out homozygotes. |
