Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_019114.5(EPB41L4B):c.1969G>A(p.Glu657Lys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,461,854 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E657D) has been classified as Uncertain significance.

Genes affected

EPB41L4B (HGNC:19818): (erythrocyte membrane protein band 4.1 like 4B) Predicted to be a structural constituent of cytoskeleton. Involved in several processes, including positive regulation of cell adhesion; positive regulation of keratinocyte migration; and wound healing. Acts upstream of or within actomyosin structure organization. Located in apical part of cell; cytosol; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]
