Genes affected

LTK (HGNC:6721): (leukocyte receptor tyrosine kinase) The protein encoded by this gene is a member of the ros/insulin receptor family of tyrosine kinases. Tyrosine-specific phosphorylation of proteins is a key to the control of diverse pathways leading to cell growth and differentiation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

The c.1958G>A (p.C653Y) alteration is located in exon 16 (coding exon 16) of the LTK gene. This alteration results from a G to A substitution at nucleotide position 1958, causing the cysteine (C) at amino acid position 653 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
