Genes affected
SPIRE1 (HGNC:30622): (spire type actin nucleation factor 1) Spire proteins, such as SPIRE1, are highly conserved between species. They belong to the family of Wiskott-Aldrich homology region-2 (WH2) proteins, which are involved in actin organization (Kerkhoff et al., 2001 [PubMed 11747823]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.2224G>C (p.G742R) alteration is located in exon 17 (coding exon 17) of the SPIRE1 gene. This alteration results from a G to C substitution at nucleotide position 2224, causing the glycine (G) at amino acid position 742 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
