Genes affected
TCEAL8 (HGNC:28683): (transcription elongation factor A like 8) This gene encodes a member of the transcription elongation factor A (SII)-like (TCEAL) gene family. Members of this family contain TFA domains and may function as nuclear phosphoproteins that modulate transcription in a promoter context-dependent manner. Multiple family members are located on the X chromosome. Alternative splicing results in multiple transcript variants encoding a single isoform. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2023The c.235G>A (p.V79I) alteration is located in exon 3 (coding exon 1) of the TCEAL8 gene. This alteration results from a G to A substitution at nucleotide position 235, causing the valine (V) at amino acid position 79 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
