Genes affected
WASHC2C (HGNC:23414): (WASH complex subunit 2C) Enables phosphatidylinositol phosphate binding activity; phosphatidylinositol-3,4-bisphosphate binding activity; and retromer complex binding activity. Involved in several processes, including endosomal transport; negative regulation of barbed-end actin filament capping; and regulation of substrate adhesion-dependent cell spreading. Located in cytosol; early endosome; and nucleolus. Part of WASH complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.740C>T (p.T247I) alteration is located in exon 9 (coding exon 9) of the FAM21C gene. This alteration results from a C to T substitution at nucleotide position 740, causing the threonine (T) at amino acid position 247 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
