Haploinsufficiency (HI) Score Details

HI Score:
3
HI Evidence Strength:
Sufficient Evidence for Haploinsufficiency (Disclaimer)
HI Disease:
  • spondyloepiphyseal dysplasia tarda, X-linked Monarch
HI Evidence:
  • PUBMED: 11252002
    Matsui et al. 2001: An intragenic deletion including the 5' untranslated region but also the coding sequence for the first methionine through the 25th alanine was found in a Japanese male with X-linked spondyloepiphyseal dysplasia tarda and his carrier mother, but not in his unaffected sister or uncle.
  • PUBMED: 12919139
    Shaw et al. 2003: A 1,335bp intragenic deletion (in5/ex6del), was found in a Belgian patient resulting in X-linked spondyloepiphyseal dysplasia tarda.
  • PUBMED: 11349230
    Gedeon et al. 2001: Describes the mutations found in 30 unrelated individuals with X-linked sponkyloepiphyseal dysplasia tarda, including multiple nonsense mutations and two exonic deletions (one involving exon 3, and another involving exon 6).
HI Evidence Comments:
Alterations of TRAPPC2 have been associated with X-linked spondyloepiphyseal dysplasia tarda. From GeneReviews: "One report described phenotypically normal females with mild radiologically detectable osteoarthritic changes [Whyte et al 1999]. "
NOTE:

The loss-of-function and triplosensitivity ratings for genes on the X chromosome are made in the context of a male genome to account for the effects of hemizygous duplications or nullizygous deletions. In contrast, disruption of some genes on the X chromosome causes male lethality and the ratings of dosage sensitivity instead take into account the phenotype in female individuals. Factors that may affect the severity of phenotypes associated with X-linked disorders include the presence of variable copies of the X chromosome (i.e. 47,XXY or 45,X) and skewed X-inactivation in females.
