Genes affected

PLAGL1 (HGNC:9046): (PLAG1 like zinc finger 1) This gene encodes a C2H2 zinc finger protein that functions as a suppressor of cell growth. This gene is often deleted or methylated and silenced in cancer cells. In addition, overexpression of this gene during fetal development is thought to be the causal factor for transient neonatal diabetes mellitus (TNDM). Alternative splicing and the use of alternative promoters results in multiple transcript variants encoding two different protein isoforms. The P1 downstream promoter of this gene is imprinted, with preferential expression from the paternal allele in many tissues. [provided by RefSeq, Nov 2015]

The c.818A>G (p.Q273R) alteration is located in exon 7 (coding exon 2) of the PLAGL1 gene. This alteration results from a A to G substitution at nucleotide position 818, causing the glutamine (Q) at amino acid position 273 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
