Genes affected

ELF1 (HGNC:3316): (E74 like ETS transcription factor 1) This gene encodes an E26 transformation-specific related transcription factor. The encoded protein is primarily expressed in lymphoid cells and acts as both an enhancer and a repressor to regulate transcription of various genes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2009]

ACMG classification

Verdict is Likely_benign. Variant got -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.0721046).
• BS2: High AC in GnomAdExome4 at 5 AD gene.

Collection Method: clinical testing

The c.1850A>C (p.N617T) alteration is located in exon 9 (coding exon 8) of the ELF1 gene. This alteration results from a A to C substitution at nucleotide position 1850, causing the asparagine (N) at amino acid position 617 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
