Genes affected

ZNF664-RFLNA (HGNC:):

RFLNA (HGNC:27051): (refilin A) Predicted to enable filamin binding activity. Predicted to be involved in several processes, including actin filament bundle organization; negative regulation of bone mineralization involved in bone maturation; and negative regulation of chondrocyte development. Predicted to be located in cytoplasm. Predicted to be active in actin filament bundle. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.
