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.128C>A (p.A43D) alteration is located in exon 2 (coding exon 1) of the TCF19 gene. This alteration results from a C to A substitution at nucleotide position 128, causing the alanine (A) at amino acid position 43 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
