Genes affected

AXL (HGNC:905): (AXL receptor tyrosine kinase) The protein encoded by this gene is a member of the Tyro3-Axl-Mer (TAM) receptor tyrosine kinase subfamily. The encoded protein possesses an extracellular domain which is composed of two immunoglobulin-like motifs at the N-terminal, followed by two fibronectin type-III motifs. It transduces signals from the extracellular matrix into the cytoplasm by binding to the vitamin K-dependent protein growth arrest-specific 6 (Gas6). This gene may be involved in several cellular functions including growth, migration, aggregation and anti-inflammation in multiple cell types. The encoded protein acts as a host cell receptor for multiple viruses, including Marburg, Ebola and Lassa viruses and is a candidate receptor for the SARS-CoV2 virus. [provided by RefSeq, Sep 2021]

Variant summary: AXL c.236C>T (p.Ala79Val) results in a non-conservative amino acid change located in the Immunoglobulin-like domain (IPR007110) of the encoded protein sequence. Three of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.00028 in 251344 control chromosomes. This frequency does not allow for any conclusion about variant significance. To our knowledge, no occurrence of c.236C>T in individuals affected with Hypogonadotropic Hypogonadism 7 With Or Without Anosmia and no experimental evidence demonstrating its impact on protein function have been reported. One submitter has cited clinical-significance assessments for this variant to ClinVar after 2014 and has classified the variant as likely benign. Based on the evidence outlined above, the variant was classified as uncertain significance. -
