Genes affected
TCF19 (HGNC:11629): (transcription factor 19) This gene encodes a protein that contains a PHD-type zinc finger domain and likely functions as a transcription factor. The encoded protein plays a role proliferation and apoptosis of pancreatic beta cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]

The c.196G>A (p.G66S) alteration is located in exon 2 (coding exon 1) of the TCF19 gene. This alteration results from a G to A substitution at nucleotide position 196, causing the glycine (G) at amino acid position 66 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
