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.

Ambry Genetics

Dec 17, 2023

The c.20G>C (p.C7S) alteration is located in exon 1 (coding exon 1) of the SPIRE2 gene. This alteration results from a G to C substitution at nucleotide position 20, causing the cysteine (C) at amino acid position 7 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
