Genes affected

CIBAR1 (HGNC:30452): (CBY1 interacting BAR domain containing 1) Enables phospholipid binding activity. Involved in several processes, including inner mitochondrial membrane organization; limb morphogenesis; and membrane tubulation. Located in several cellular components, including centriole; ciliary base; and mitochondrial crista. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a mutagenesis_site Reduced membrane-binding and significant reduction in membrane remodeling activity; when associated with A-132 and A-136. (size 0) in uniprot entity CBAR1_HUMAN
• PM2: Very rare variant in population databases, with high coverage
