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.402C>A (p.N134K) alteration is located in exon 3 (coding exon 3) of the SPIRE2 gene. This alteration results from a C to A substitution at nucleotide position 402, causing the asparagine (N) at amino acid position 134 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
