Genes affected
TBX15 (HGNC:11594): (T-box transcription factor 15) This gene belongs to the T-box family of genes, which encode a phylogenetically conserved family of transcription factors that regulate a variety of developmental processes. All these genes contain a common T-box DNA-binding domain. Mutations in this gene are associated with Cousin syndrome.[provided by RefSeq, Oct 2009]

The c.1325C>T (p.S442F) alteration is located in exon 8 (coding exon 7) of the TBX15 gene. This alteration results from a C to T substitution at nucleotide position 1325, causing the serine (S) at amino acid position 442 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
