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]

Ambry Genetics

Sep 20, 2023

The c.1991G>A (p.R664Q) alteration is located in exon 16 (coding exon 16) of the SPIRE1 gene. This alteration results from a G to A substitution at nucleotide position 1991, causing the arginine (R) at amino acid position 664 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
