Genes affected

SPIRE2 (HGNC:30623): (spire type actin nucleation factor 2) Predicted to enable actin binding activity. Involved in establishment of meiotic spindle localization; formin-nucleated actin cable assembly; and positive regulation of double-strand break repair. Predicted to be located in cytoskeleton; cytosol; and plasma membrane. Predicted to be active in cell cortex and cytoplasmic vesicle membrane. Predicted to colocalize with cleavage furrow.

The c.187G>T (p.G63W) alteration is located in exon 1 (coding exon 1) of the SPIRE2 gene. This alteration results from a G to T substitution at nucleotide position 187, causing the glycine (G) at amino acid position 63 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
