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.706G>A (p.V236I) alteration is located in exon 5 (coding exon 5) of the CRLF3 gene. This alteration results from a G to A substitution at nucleotide position 706, causing the valine (V) at amino acid position 236 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
