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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.2281C>T (p.P761S) alteration is located in exon 23 (coding exon 22) of the ANKRD27 gene. This alteration results from a C to T substitution at nucleotide position 2281, causing the proline (P) at amino acid position 761 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
