Genes affected

CUL7 (HGNC:21024): (cullin 7) The protein encoded by this gene is a component of an E3 ubiquitin-protein ligase complex. The encoded protein interacts with TP53, CUL9, and FBXW8 proteins. Defects in this gene are a cause of 3M syndrome type 1 (3M1). Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

The c.3797A>G (p.H1266R) alteration is located in exon 20 (coding exon 19) of the CUL7 gene. This alteration results from a A to G substitution at nucleotide position 3797, causing the histidine (H) at amino acid position 1266 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
