Haploinsufficiency phenotype comments:

As part of an effort to identify genomic regions that are unlikely to be dosage sensitive, ClinGen queried the Database of Genomic Variants (DGV) gold standard GRCh37 data set (PMID: 24174537) (downloaded June 2021) for variants meeting the following criteria: passed DGV quality filters, characterized as either a deletion or duplication, >1 kb in size, includes at least one gene, and present at an allele frequency of >5% (with at least 2000 alleles tested). This region corresponds to a variant identified as meeting those criteria in DGV gold standard GRCh37; the DGV gold standard GRCh37 identifier for this variant is reflected in the title for reference. As of July 1st, 2021, there has been no reported relationship between the gene(s) included in this region and human disease. Given the high population frequency, this region has been classified as ?dosage sensitivity unlikely?.

The ratings for loss-of-function and triplosensitivity for genes on the Y chromosome are made in the same fashion as for genes linked to autosomal dominant disorders.

  • Triplosensitivity score: 0
  • Strength of Evidence (disclaimer): No evidence for dosage pathogenicity
