Genes affected

UNC45A (HGNC:30594): (unc-45 myosin chaperone A) This gene encodes a regulatory component of the progesterone receptor/heat shock protein 90 chaperoning complex, which functions in the assembly and folding of the progesterone receptor. The encoded protein is thought to be essential for normal cell proliferation, and for the accumulation of myosin during development of muscle cells. [provided by RefSeq, Sep 2018]

HDDC3 (HGNC:30522): (HD domain containing 3) Predicted to enable guanosine-3',5'-bis(diphosphate) 3'-diphosphatase activity. [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=-0.57).
• BP7: Synonymous conserved (PhyloP=-1.8 with no splicing effect.
