Genes affected

MTSS1 (HGNC:20443): (MTSS I-BAR domain containing 1) Enables actin monomer binding activity; identical protein binding activity; and signaling receptor binding activity. Predicted to be involved in cellular response to fluid shear stress; negative regulation of epithelial cell proliferation; and urogenital system development. Predicted to act upstream of or within several processes, including actin filament polymerization; adherens junction maintenance; and magnesium ion homeostasis. Located in actin cytoskeleton.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0304 (4627/152194) while in subpopulation NFE AF= 0.0437 (2974/68010). AF 95% confidence interval is 0.0424. There are 117 homozygotes in gnomad4. There are 2341 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 4627 AD gene.
