Genes affected

RUFY3 (HGNC:30285): (RUN and FYVE domain containing 3) This gene encodes a RPIP8, UNC-14, and NESCA domain-containing protein that is required for maintenance of neuronal polarity. In addition, it has been implicated in mediation of gastric cancer cell migration and invasion via interaction with P21-activated kinase-1, which promotes its expression. The encoded protein localizes to F-actin-enriched invadopodia to induce formation of protrusions, thereby facilitating cell migration. Alternative splicing results in multiple transcript variants.

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP6: Variant 4-70773581-A-G is Benign according to our data. Variant chr4-70773581-A-G is described in ClinVar as Benign. ClinVar VariationId is 720186.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00814 (1240/152332) while in subpopulation AFR AF = 0.0284 (1179/41580). AF 95% confidence interval is 0.027. There are 15 homozygotes in GnomAd4. There are 587 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 15 AR gene
