Genes affected

SP5 (HGNC:14529): (Sp5 transcription factor) Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within bone morphogenesis; cellular response to organic cyclic compound; and post-anal tail morphogenesis. Predicted to be located in nucleus. Predicted to be part of chromatin. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.452C>G (p.A151G) alteration is located in exon 2 (coding exon 2) of the SP5 gene. This alteration results from a C to G substitution at nucleotide position 452, causing the alanine (A) at amino acid position 151 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
