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 GeneticsNov 21, 2022The c.1204C>T (p.R402C) alteration is located in exon 9 (coding exon 9) of the TRPC4AP gene. This alteration results from a C to T substitution at nucleotide position 1204, causing the arginine (R) at amino acid position 402 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
