Genes affected

GTF2IRD1 (HGNC:4661): (GTF2I repeat domain containing 1) The protein encoded by this gene contains five GTF2I-like repeats and each repeat possesses a potential helix-loop-helix (HLH) motif. It may have the ability to interact with other HLH-proteins and function as a transcription factor or as a positive transcriptional regulator under the control of Retinoblastoma protein. This gene plays a role in craniofacial and cognitive development and mutations have been associated with Williams-Beuren syndrome, a multisystem developmental disorder caused by deletion of multiple genes at 7q11.23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2010]

The c.323G>C (p.R108P) alteration is located in exon 4 (coding exon 3) of the GTF2IRD1 gene. This alteration results from a G to C substitution at nucleotide position 323, causing the arginine (R) at amino acid position 108 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
