Genes affected

DOK5 (HGNC:16173): (docking protein 5) The protein encoded by this gene is a member of the DOK family of membrane proteins, which are adapter proteins involved in signal transduction. The encoded protein interacts with phosphorylated receptor tyrosine kinases to mediate neurite outgrowth and activation of the MAP kinase pathway. Unlike other DOK family proteins, this protein does not interact with RASGAP. This protein is up-regulated in patients with systemic sclerosis and is associated with fibrosis induced by insulin-like growth factor binding protein 5. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jun 2014]

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0059 (568/96196) while in subpopulation AFR AF= 0.02 (538/26932). AF 95% confidence interval is 0.0186. There are 4 homozygotes in gnomad4. There are 263 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 4 AR gene
