Genes affected

TCP10L (HGNC:11657): (t-complex 10 like) Enables several functions, including identical protein binding activity; protein self-association; and transcription corepressor activity. Involved in negative regulation of transcription by RNA polymerase II. Located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

TCP10L links:

CFAP298-TCP10L (HGNC:54636): (CFAP298-TCP10L readthrough) This locus represents naturally occurring readthrough transcription between the neighboring chromosome 21 open reading frame 59 (C21orf59) and TCP10L (t-complex 10 like) genes on chromosome 21. Readthrough transcripts may encode a fusion protein that shares sequence identity with each individual gene product. [provided by RefSeq, Apr 2017]

The c.640G>A (p.G214S) alteration is located in exon 5 (coding exon 4) of the TCP10L gene. This alteration results from a G to A substitution at nucleotide position 640, causing the glycine (G) at amino acid position 214 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
