Variant summary

Our verdict is Likely benign. Variant got -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP7

The ENST00000393033.9(GIPC1):​c.852G>C​(p.Ala284=) variant causes a splice region, 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. 3/3 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. A284A) has been classified as Benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: GIPC1 ENST00000393033.9 splice_region, synonymous
• Scores: Splicing: ADA: 0.0001068
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.762

Genes affected

GIPC1 (HGNC:1226): (GIPC PDZ domain containing family member 1) GIPC1 is a scaffolding protein that regulates cell surface receptor expression and trafficking (Lee et al., 2008 [PubMed 18775991]).[supplied by OMIM, Apr 2009]

ACMG classification

Verdict is Likely_benign. Variant got -1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.35).
• BP7: Synonymous conserved (PhyloP=-0.762 with no splicing effect.
