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. [provided by RefSeq, Apr 2012]
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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 19, 2024The c.3250T>C (p.Y1084H) alteration is located in exon 23 (coding exon 23) of the ANKFY1 gene. This alteration results from a T to C substitution at nucleotide position 3250, causing the tyrosine (Y) at amino acid position 1084 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
