Genes affected
RCHY1 (HGNC:17479): (ring finger and CHY zinc finger domain containing 1) The protein encoded by this gene has ubiquitin ligase activity. It mediates E3-dependent ubiquitination and proteasomal degradation of target proteins, including tumor protein 53, histone deacetylase 1, and cyclin-dependent kinase inhibitor 1B, thus regulating their levels and cell cycle progression. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Jun 2013]
THAP6 (HGNC:23189): (THAP domain containing 6) Predicted to enable DNA binding activity and metal ion binding activity. Located in microtubule cytoskeleton. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 18, 2024The c.68A>G (p.Y23C) alteration is located in exon 1 (coding exon 1) of the RCHY1 gene. This alteration results from a A to G substitution at nucleotide position 68, causing the tyrosine (Y) at amino acid position 23 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
