Genes affected

ZNF664 (HGNC:25406): (zinc finger protein 664) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription, DNA-templated. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

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

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.66).
• BP7: Synonymous conserved (PhyloP=-0.139 with no splicing effect.
