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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.74A>G (p.E25G) alteration is located in exon 1 (coding exon 1) of the SPIRE2 gene. This alteration results from a A to G substitution at nucleotide position 74, causing the glutamic acid (E) at amino acid position 25 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
