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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 10, 2024The c.383T>C (p.I128T) alteration is located in exon 3 (coding exon 2) of the LRRC8E gene. This alteration results from a T to C substitution at nucleotide position 383, causing the isoleucine (I) at amino acid position 128 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
