Genes affected

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]

HDDC3 links:

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]

Feb 14, 2023

The c.332G>A (p.S111N) alteration is located in exon 3 (coding exon 3) of the HDDC3 gene. This alteration results from a G to A substitution at nucleotide position 332, causing the serine (S) at amino acid position 111 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
