Genes affected
TRPC4AP (HGNC:16181): (transient receptor potential cation channel subfamily C member 4 associated protein) Enables phosphatase binding activity and ubiquitin ligase-substrate adaptor activity. Involved in protein ubiquitination and ubiquitin-dependent protein catabolic process via the C-end degron rule pathway. Part of Cul4A-RING E3 ubiquitin ligase complex. Is active in Cul4-RING E3 ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 16, 2023The c.1961G>A (p.R654H) alteration is located in exon 17 (coding exon 17) of the TRPC4AP gene. This alteration results from a G to A substitution at nucleotide position 1961, causing the arginine (R) at amino acid position 654 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
