Genes affected
INSRR (HGNC:6093): (insulin receptor related receptor) Enables transmembrane receptor protein tyrosine kinase activity. Involved in actin cytoskeleton reorganization; cellular response to alkaline pH; and protein autophosphorylation. Part of receptor complex. [provided by Alliance of Genome Resources, Apr 2022]
NTRK1 (HGNC:8031): (neurotrophic receptor tyrosine kinase 1) This gene encodes a member of the neurotrophic tyrosine kinase receptor (NTKR) family. This kinase is a membrane-bound receptor that, upon neurotrophin binding, phosphorylates itself and members of the MAPK pathway. The presence of this kinase leads to cell differentiation and may play a role in specifying sensory neuron subtypes. Mutations in this gene have been associated with congenital insensitivity to pain, anhidrosis, self-mutilating behavior, cognitive disability and cancer. Alternate transcriptional splice variants of this gene have been found, but only three have been characterized to date. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 09, 2021The c.3748C>A (p.L1250M) alteration is located in exon 22 (coding exon 22) of the INSRR gene. This alteration results from a C to A substitution at nucleotide position 3748, causing the leucine (L) at amino acid position 1250 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
