Genes affected

RAET1E (HGNC:16793): (retinoic acid early transcript 1E) This gene belong to the RAET1 family, which consists of major histocompatibility complex (MHC) class I-related genes located in a cluster on chromosome 6q24.2-q25.3. This and RAET1G protein differ from other RAET1 proteins in that they have type I membrane-spanning sequences at their C termini rather than glycosylphosphatidylinositol anchor sequences. This protein functions as a ligand for NKG2D receptor, which is expressed on the surface of several types of immune cells, and is involved in innate and adaptive immune responses. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Aug 2011]

RAET1E-LRP11 (HGNC:):

RAET1E-AS1 (HGNC:48994): (RAET1E antisense RNA 1)

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2693052).

The c.538T>A (p.Y180N) alteration is located in exon 1 (coding exon 1) of the RAET1E gene. This alteration results from a T to A substitution at nucleotide position 538, causing the tyrosine (Y) at amino acid position 180 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
