Genes affected

ZGRF1 (HGNC:25654): (zinc finger GRF-type containing 1) The encoded protein contains GRF zinc finger (zf-GRF) and transmembrane domains. GRF zinc fingers are found in a number of DNA-binding proteins. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Apr 2017]

The c.6051T>G (p.I2017M) alteration is located in exon 27 (coding exon 26) of the ZGRF1 gene. This alteration results from a T to G substitution at nucleotide position 6051, causing the isoleucine (I) at amino acid position 2017 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
