Genes affected

EGR1 (HGNC:3238): (early growth response 1) The protein encoded by this gene belongs to the EGR family of C2H2-type zinc-finger proteins. It is a nuclear protein and functions as a transcriptional regulator. The products of target genes it activates are required for differentitation and mitogenesis. Studies suggest this is a cancer suppressor gene. [provided by RefSeq, Dec 2014]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.98

The c.1072C>T (p.H358Y) alteration is located in exon 2 (coding exon 2) of the EGR1 gene. This alteration results from a C to T substitution at nucleotide position 1072, causing the histidine (H) at amino acid position 358 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
