Genes affected

CRLF3 (HGNC:17177): (cytokine receptor like factor 3) This gene encodes a cytokine receptor-like factor that may negatively regulate cell cycle progression at the G0/G1 phase. Studies of the related rat protein suggest that it may regulate neuronal morphology and synaptic vesicle biogenesis. This gene is one of several genes located in the neurofibromatosis type I tumor suppressor region on the q arm of chromosome 17, a region that is subject to microdeletions, duplications, chromosomal breaks and rearrangements. Alternative splicing of this gene results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 2 and 5. [provided by RefSeq, Aug 2012]

The c.1043G>A (p.R348Q) alteration is located in exon 7 (coding exon 7) of the CRLF3 gene. This alteration results from a G to A substitution at nucleotide position 1043, causing the arginine (R) at amino acid position 348 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
