Genes affected

GGPS1 (HGNC:4249): (geranylgeranyl diphosphate synthase 1) This gene is a member of the prenyltransferase family and encodes a protein with geranylgeranyl diphosphate (GGPP) synthase activity. The enzyme catalyzes the synthesis of GGPP from farnesyl diphosphate and isopentenyl diphosphate. GGPP is an important molecule responsible for the C20-prenylation of proteins and for the regulation of a nuclear hormone receptor. Alternate transcriptional splice variants, both protein-coding and non-protein-coding, have been found for this gene. [provided by RefSeq, Sep 2010]

The c.49A>G (p.K17E) alteration is located in exon 2 (coding exon 1) of the GGPS1 gene. This alteration results from a A to G substitution at nucleotide position 49, causing the lysine (K) at amino acid position 17 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
