Genes affected

ANKRD27 (HGNC:25310): (ankyrin repeat domain 27) Enables guanyl-nucleotide exchange factor activity and small GTPase binding activity. Involved in endocytic recycling and negative regulation of SNARE complex assembly. Acts upstream of or within early endosome to late endosome transport. Located in endosome; lysosome; and plasma membrane. Implicated in eosinophilic esophagitis. [provided by Alliance of Genome Resources, Apr 2022]

The c.2267G>C (p.R756P) alteration is located in exon 23 (coding exon 22) of the ANKRD27 gene. This alteration results from a G to C substitution at nucleotide position 2267, causing the arginine (R) at amino acid position 756 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
