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_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.81).
• BP6: Variant 2-113242674-G-A is Benign according to our data. Variant chr2-113242674-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 259050.Status of the report is criteria_provided_single_submitter, 1 stars.
