Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_001004416.3(UMODL1):​c.3537T>A​(p.Pro1179Pro) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. P1179P) has been classified as Likely benign.

Genes affected

UMODL1 (HGNC:12560): (uromodulin like 1) Predicted to be an extracellular matrix structural constituent. Predicted to be involved in neutrophil migration. Predicted to act upstream of or within several processes, including adipose tissue development; cellular response to gonadotropin-releasing hormone; and regulation of ovarian follicle development. Predicted to be located in cytoplasm and external side of plasma membrane. Predicted to be integral component of membrane. Predicted to be active in apical plasma membrane; cell surface; and extracellular space. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.93).
• BP7: Synonymous conserved (PhyloP=-4.45 with no splicing effect.
