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]

The c.574A>G (p.I192V) alteration is located in exon 2 (coding exon 2) of the SP5 gene. This alteration results from a A to G substitution at nucleotide position 574, causing the isoleucine (I) at amino acid position 192 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
