Genes affected

ZBTB1 (HGNC:20259): (zinc finger and BTB domain containing 1) Enables K63-linked polyubiquitin modification-dependent protein binding activity; protein heterodimerization activity; and protein homodimerization activity. Involved in several processes, including cellular response to UV; nucleobase-containing compound biosynthetic process; and protein homooligomerization. Located in centrosome; nuclear body; and nuclear membrane. [provided by Alliance of Genome Resources, Apr 2022]

HSPA2-AS1 (HGNC:55433): (HSPA2 and ZBTB1 antisense RNA 1)

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
