Genes affected

RYK (HGNC:10481): (receptor like tyrosine kinase) The protein encoded by this gene is an atypical member of the family of growth factor receptor protein tyrosine kinases, differing from other members at a number of conserved residues in the activation and nucleotide binding domains. This gene product belongs to a subfamily whose members do not appear to be regulated by phosphorylation in the activation segment. It has been suggested that mediation of biological activity by recruitment of a signaling-competent auxiliary protein may occur through an as yet uncharacterized mechanism. The encoded protein has a leucine-rich extracellular domain with a WIF-type Wnt binding region, a single transmembrane domain, and an intracellular tyrosine kinase domain. This protein is involved in stimulating Wnt signaling pathways such as the regulation of axon pathfinding. Alternative splicing results in multiple transcript variants encoding distinct isoforms.

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BP6: Variant 3-134191843-A-C is Benign according to our data. Variant chr3-134191843-A-C is described in ClinVar as [Benign]. Clinvar id is 2654162.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population mid. gnomad4_exome allele frequency = 0.0132 (19047/1445940) while in subpopulation MID AF= 0.0206 (118/5730). AF 95% confidence interval is 0.0176. There are 157 homozygotes in gnomad4_exome. There are 9236 alleles in male gnomad4_exome subpopulation. Median coverage is 29. This position pass quality control queck.
• BS2: High AC in GnomAd at 1385 AD gene.
