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 Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a DNA_binding_region Paired (size 126) in uniprot entity PAX8_HUMAN there are 22 pathogenic changes around while only 4 benign (85%) in NM_003466.4
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.937
