Genes affected

SP7 (HGNC:17321): (Sp7 transcription factor) This gene encodes a member of the Sp subfamily of Sp/XKLF transcription factors. Sp family proteins are sequence-specific DNA-binding proteins characterized by an amino-terminal trans-activation domain and three carboxy-terminal zinc finger motifs. This protein is a bone specific transcription factor and is required for osteoblast differentiation and bone formation.[provided by RefSeq, Jul 2010]

Ambry Genetics

Feb 14, 2023

The c.1253C>T (p.A418V) alteration is located in exon 3 (coding exon 2) of the SP7 gene. This alteration results from a C to T substitution at nucleotide position 1253, causing the alanine (A) at amino acid position 418 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
