Genes affected

GAB2 (HGNC:14458): (GRB2 associated binding protein 2) This gene is a member of the GRB2-associated binding protein (GAB) gene family. These proteins contain pleckstrin homology (PH) domain, and bind SHP2 tyrosine phosphatase and GRB2 adapter protein. They act as adapters for transmitting various signals in response to stimuli through cytokine and growth factor receptors, and T- and B-cell antigen receptors. The protein encoded by this gene is the principal activator of phosphatidylinositol-3 kinase in response to activation of the high affinity IgE receptor. Two alternatively spliced transcripts encoding different isoforms have been described for this gene. [provided by RefSeq, Nov 2009]

USP35 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.009805918).
• BP6: Variant 11-78226722-G-A is Benign according to our data. Variant chr11-78226722-G-A is described in ClinVar as [Benign]. Clinvar id is 718663.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-78226722-G-A is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population eas. gnomad4_exome allele frequency = 0.00103 (1512/1461764) while in subpopulation EAS AF= 0.0259 (1028/39700). AF 95% confidence interval is 0.0246. There are 17 homozygotes in gnomad4_exome. There are 717 alleles in male gnomad4_exome subpopulation. Median coverage is 35. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 141 AD gene.
