Genes affected
TCEAL1 (HGNC:11616): (transcription elongation factor A like 1) This gene encodes a member of the transcription elongation factor A (SII)-like (TCEAL) gene family. Members of this family may function as nuclear phosphoproteins that modulate transcription in a promoter context-dependent manner. The encoded protein is similar to transcription elongation factor A/transcription factor SII and contains a zinc finger-like motif as well as a sequence related to the transcription factor SII Pol II-binding region. It may exert its effects via protein-protein interactions with other transcriptional regulators rather than via direct binding of DNA. 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]

Variant summary: TCEAL1 c.413A>G (p.Lys138Arg) results in a conservative amino acid change in the encoded protein sequence. Four of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 4.8e-05 in 1210364 control chromosomes including 16 hemizygotes suggesting a benign role for the variant. To our knowledge, no occurrence of c.413A>G in individuals affected with Neurodevelopmental Disorder With Gait Disturbance, Dysmorphic Facies, And Behavioral Abnormalities, X-Linked and no experimental evidence demonstrating its impact on protein function have been reported. No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as likely benign. -
