Genes affected

DUOXA2 (HGNC:32698): (dual oxidase maturation factor 2) This gene encodes an endoplasmic reticulum protein that is necessary for proper cellular localization and maturation of functional dual oxidase 2. Mutations in this gene have been associated with thyroid dyshormonogenesis 5.[provided by RefSeq, Feb 2010]

DUOXA2 Gene-Disease associations (from GenCC):

• thyroid dyshormonogenesis 5

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Labcorp Genetics (formerly Invitae), Ambry Genetics
• familial thyroid dyshormonogenesis

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_pathogenic. The variant received 6 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.060228452 fraction of the gene. Cryptic splice site detected, with MaxEntScore 5.5, offset of 36, new splice context is: gggGTgagg. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 15-45115857-G-A is Pathogenic according to our data. Variant chr15-45115857-G-A is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 3577209.Status of the report is criteria_provided_single_submitter, 1 stars.
