GRCh37/hg19 chrY: 23,656,999-23,713,300 ()

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

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: Triplosensitivity unlikely
  • Strength of Evidence (disclaimer): Triplosensitivity unlikely

Triplosensitivity phenotype comment:

As part of an effort to identify genomic regions that are unlikely to be dosage sensitive, ClinGen queried the gnomAD structural variant (SV) v2.1 data set (PMID: 32461652) for variants meeting the following criteria: passed gnomAD quality filters, characterized as either a deletion or duplication, >1kb 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 these criteria in gnomAD-SV v2.1; the gnomAD identifier for this variant is reflected in the title for reference. As of May 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.?
