Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_001012338.3(NTRK3):​c.41G>T​(p.Arg14Leu) variant causes a missense change. The variant allele was found at a frequency of 0.000000684 in 1,460,964 control chromosomes in the GnomAD database, with no homozygous occurrence. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R14Q) has been classified as Uncertain significance.

Genes affected

NTRK3 (HGNC:8033): (neurotrophic receptor tyrosine kinase 3) This gene encodes a member of the neurotrophic tyrosine receptor kinase (NTRK) family. This kinase is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. Signalling through this kinase leads to cell differentiation and may play a role in the development of proprioceptive neurons that sense body position. Mutations in this gene have been associated with medulloblastomas, secretory breast carcinomas and other cancers. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2011]

NTRK3-AS1 (HGNC:27532): (NTRK3 antisense RNA 1)
