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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.236T>C (p.I79T) alteration is located in exon 3 (coding exon 2) of the TCP10L gene. This alteration results from a T to C substitution at nucleotide position 236, causing the isoleucine (I) at amino acid position 79 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
