Genes affected

TASOR (HGNC:30314): (transcription activation suppressor) Enables chromatin binding activity. Involved in negative regulation of single stranded viral RNA replication via double stranded DNA intermediate; protein localization to heterochromatin; and regulation of gene expression. Located in heterochromatin and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.
