Genes affected

TCEAL4 (HGNC:26121): (transcription elongation factor A like 4) This gene encodes a member of the transcription elongation factor A (SII)-like (TCEAL) gene family. This family is comprised of nuclear phosphoproteins that modulate transcription in a promoter context-dependent manner. Multiple family members are located on the X chromosome. Alternatively splicing results in multiple transcript variants. There is a pseudogene for this gene on chromosome 13. [provided by RefSeq, Apr 2015]

ACMG classification

Verdict is Benign. Variant got -9 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.034282207).
• BP6: Variant X-103587300-A-G is Benign according to our data. Variant chrX-103587300-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 2661098.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
• BS2: High Hemizygotes in GnomAd4 at 2 gene

The c.625A>G (p.I209V) alteration is located in exon 3 (coding exon 1) of the TCEAL4 gene. This alteration results from a A to G substitution at nucleotide position 625, causing the isoleucine (I) at amino acid position 209 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
