Genes affected

ANKFY1 (HGNC:20763): (ankyrin repeat and FYVE domain containing 1) This gene encodes a cytoplasmic protein that contains a coiled-coil structure and a BTB/POZ domain at its N-terminus, ankyrin repeats in the middle portion, and a FYVE-finger motif at its C-terminus. This protein belongs to a subgroup of double zinc finger proteins which may be involved in vesicle or protein transport. Alternate splicing results in multiple transcript variants of this gene.

CYB5D2 (HGNC:28471): (cytochrome b5 domain containing 2) Predicted to enable heme binding activity. Predicted to be involved in nervous system development. Predicted to act upstream of or within positive regulation of neuron differentiation. Predicted to be located in extracellular region. Predicted to be active in endomembrane system and membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
