Genes affected

PAX8 (HGNC:8622): (paired box 8) This gene encodes a member of the paired box (PAX) family of transcription factors. Members of this gene family typically encode proteins that contain a paired box domain, an octapeptide, and a paired-type homeodomain. This nuclear protein is involved in thyroid follicular cell development and expression of thyroid-specific genes. Mutations in this gene have been associated with thyroid dysgenesis, thyroid follicular carcinomas and atypical follicular thyroid adenomas. Alternatively spliced transcript variants encoding different isoforms have been described. [provided by RefSeq, Mar 2010]

PAX8-AS1 (HGNC:49271): (PAX8 antisense RNA 1)

ACMG classification

Verdict is Likely_pathogenic. Variant got 7 ACMG points.

• PM1: In a region_of_interest PAI subdomain (size 56) in uniprot entity PAX8_HUMAN there are 6 pathogenic changes around while only 0 benign (100%) in NM_003466.4
• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.912
• PP5: Variant 2-113246826-T-G is Pathogenic according to our data. Variant chr2-113246826-T-G is described in ClinVar as [Pathogenic]. Clinvar id is 13788.Status of the report is no_assertion_criteria_provided, 0 stars.
