Genes affected

PTK7 (HGNC:9618): (protein tyrosine kinase 7 (inactive)) This gene encodes a member of the receptor protein tyrosine kinase family of proteins that transduce extracellular signals across the cell membrane. The encoded protein lacks detectable catalytic tyrosine kinase activity, is involved in the Wnt signaling pathway and plays a role in multiple cellular processes including polarity and adhesion. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

Nov 13, 2023

The c.958G>A (p.A320T) alteration is located in exon 6 (coding exon 6) of the PTK7 gene. This alteration results from a G to A substitution at nucleotide position 958, causing the alanine (A) at amino acid position 320 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
