Genes affected

PLS3 (HGNC:9091): (plastin 3) Plastins are a family of actin-binding proteins that are conserved throughout eukaryote evolution and expressed in most tissues of higher eukaryotes. In humans, two ubiquitous plastin isoforms (L and T) have been identified. Plastin 1 (otherwise known as Fimbrin) is a third distinct plastin isoform which is specifically expressed at high levels in the small intestine. The L isoform is expressed only in hemopoietic cell lineages, while the T isoform has been found in all other normal cells of solid tissues that have replicative potential (fibroblasts, endothelial cells, epithelial cells, melanocytes, etc.). The C-terminal 570 amino acids of the T-plastin and L-plastin proteins are 83% identical. It contains a potential calcium-binding site near the N terminus. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Feb 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00347 (386/111293) while in subpopulation AFR AF= 0.012 (368/30773). AF 95% confidence interval is 0.011. There are 1 homozygotes in gnomad4. There are 118 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
• BS2: High Hemizygotes in GnomAd4 at 118 XL gene
