Genes affected

LRRC8E (HGNC:26272): (leucine rich repeat containing 8 VRAC subunit E) This gene encodes a member of a small, conserved family of proteins with similar structure, including a string of extracellular leucine-rich repeats. A related protein was shown to be involved in B-cell development. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.646G>A (p.E216K) alteration is located in exon 3 (coding exon 2) of the LRRC8E gene. This alteration results from a G to A substitution at nucleotide position 646, causing the glutamic acid (E) at amino acid position 216 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
