Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 0P and 10B. BP4_Strong BP6_Moderate BS2

The ENST00000315869.8(TFE3):​c.1439G>C​(p.Gly480Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000979 in 1,209,577 control chromosomes in the GnomAD database, including 2 homozygotes. There are 394 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 13/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G480E) has been classified as Likely benign.

Genes affected

TFE3 (HGNC:11752): (transcription factor binding to IGHM enhancer 3) This gene encodes a basic helix-loop-helix domain-containing transcription factor that binds MUE3-type E-box sequences in the promoter of genes. The encoded protein promotes the expression of genes downstream of transforming growth factor beta (TGF-beta) signaling. This gene may be involved in chromosomal translocations in renal cell carcinomas and other cancers, resulting in the production of fusion proteins. Translocation partners include PRCC (papillary renal cell carcinoma), NONO (non-POU domain containing, octamer-binding), and ASPSCR1 (alveolar soft part sarcoma chromosome region, candidate 1), among other genes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2013]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.009028733).
• BP6: Variant X-49030447-C-G is Benign according to our data. Variant chrX-49030447-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 723210.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chrX-49030447-C-G is described in Lovd as [Benign].
• BS2: High Hemizygotes in GnomAd4 at 16 XL gene
