Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_005338.7(HIP1):​c.519T>G​(p.Ala173=) 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. A173A) has been classified as Benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: HIP1 NM_005338.7 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.80

Genes affected

HIP1 (HGNC:4913): (huntingtin interacting protein 1) The product of this gene is a membrane-associated protein that functions in clathrin-mediated endocytosis and protein trafficking within the cell. The encoded protein binds to the huntingtin protein in the brain; this interaction is lost in Huntington's disease. Alternative splicing results in multiple transcript variants.

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.79).
• BP7: Synonymous conserved (PhyloP=-1.8 with no splicing effect.
