Genes affected

ARHGAP29 (HGNC:30207): (Rho GTPase activating protein 29) Rap1 is a small GTPase that, through effectors, regulates Rho GTPase signaling. These effectors- Rasip1, Radil, and the protein encoded by this gene- translocate to the cell membrane, where they form a multiprotein complex. This complex is necessary for Rap1-induced inhibition of Rho signaling. Defects in this gene may be a cause of nonsyndromic cleft lip with or without cleft palate. [provided by RefSeq, Jun 2016]

ARHGAP29 Gene-Disease associations (from GenCC):

• cleft lip with or without cleft palate

  Inheritance: AD Classification: DEFINITIVE Submitted by: Illumina

ACMG classification

Our verdict: Pathogenic. The variant received 12 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-94189317-G-T is Pathogenic according to our data. Variant chr1-94189317-G-T is described in ClinVar as Pathogenic. ClinVar VariationId is 242340.Status of the report is criteria_provided_single_submitter, 1 stars.
