Genes affected

CCDC66 (HGNC:27709): (coiled-coil domain containing 66) Enables microtubule binding activity. Involved in cilium assembly; microtubule bundle formation; and regulation of protein localization to cilium. Located in several cellular components, including Flemming body; microtubule cytoskeleton; and photoreceptor inner segment. [provided by Alliance of Genome Resources, Apr 2022]

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 Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
