Genes affected
AFAP1 (HGNC:24017): (actin filament associated protein 1) The protein encoded by this gene is a Src binding partner. It may represent a potential modulator of actin filament integrity in response to cellular signals, and may function as an adaptor protein by linking Src family members and/or other signaling proteins to actin filaments. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]
AFAP1-AS1 (HGNC:28141): (AFAP1 antisense RNA 1) This gene produces a long non-coding RNA that is overexpressed in tumor cells and may promote cancer cell metastasis. [provided by RefSeq, Dec 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.2432A>G (p.K811R) alteration is located in exon 18 (coding exon 17) of the AFAP1 gene. This alteration results from a A to G substitution at nucleotide position 2432, causing the lysine (K) at amino acid position 811 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
