Genes affected

ARHGAP19 (HGNC:23724): (Rho GTPase activating protein 19) Members of the ARHGAP family, such as ARHGAP19, encode negative regulators of Rho GTPases (see RHOA; MIM 165390), which are involved in cell migration, proliferation, and differentiation, actin remodeling, and G1 cell cycle progression (Lv et al., 2007 [PubMed 17454002]).[supplied by OMIM, Mar 2008]

ARHGAP19 links:

ARHGAP19-SLIT1 (HGNC:48348): (ARHGAP19-SLIT1 readthrough (NMD candidate)) This locus represents naturally occurring read-through transcription between the neighboring Rho GTPase activating protein 19 (ARHGAP19) and slit homolog 1 (SLIT1) genes on chromosome 10. The read-through transcript is a candidate for nonsense-mediated mRNA decay (NMD), and is thus unlikely to produce a protein product. [provided by RefSeq, Feb 2011]

Dec 01, 2022

The c.1220G>T (p.R407L) alteration is located in exon 9 (coding exon 9) of the ARHGAP19 gene. This alteration results from a G to T substitution at nucleotide position 1220, causing the arginine (R) at amino acid position 407 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
