Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4

The NM_000614.4(CNTF):c.56G>A(p.Arg19His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000204 in 1,613,838 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R19L) has been classified as Uncertain significance.

Genes affected

CNTF (HGNC:2169): (ciliary neurotrophic factor) The protein encoded by this gene is a polypeptide hormone whose actions appear to be restricted to the nervous system where it promotes neurotransmitter synthesis and neurite outgrowth in certain neuronal populations. The protein is a potent survival factor for neurons and oligodendrocytes and may be relevant in reducing tissue destruction during inflammatory attacks. A mutation in this gene, which results in aberrant splicing, leads to ciliary neurotrophic factor deficiency, but this phenotype is not causally related to neurologic disease. A read-through transcript variant composed of the upstream ZFP91 gene and CNTF sequence has been identified, but it is thought to be non-coding. Read-through transcription of ZFP91 and CNTF has also been observed in mouse. [provided by RefSeq, Oct 2010]

CNTF links:

ZFP91-CNTF (HGNC:33441): (ZFP91-CNTF readthrough (NMD candidate)) This gene represents a read-through transcript composed of ZFP91 and CNTF sequence. This transcript is thought to be non-coding because it would be subject to nonsense-mediated mRNA decay (NMD). Read-through transcription of ZFP91 and CNTF has also been observed in mouse.
