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 GeneticsNov 09, 2024The c.2386C>T (p.P796S) alteration is located in exon 17 (coding exon 16) of the AFAP1 gene. This alteration results from a C to T substitution at nucleotide position 2386, causing the proline (P) at amino acid position 796 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
