Genes affected
SRGAP1 (HGNC:17382): (SLIT-ROBO Rho GTPase activating protein 1) The protein encoded by this gene is a GTPase activator, working with the GTPase CDC42 to negatively regulate neuronal migration. The encoded protein interacts with the transmembrane receptor ROBO1 to inactivate CDC42. [provided by RefSeq, Sep 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 10, 2023The c.452A>T (p.H151L) alteration is located in exon 4 (coding exon 4) of the SRGAP1 gene. This alteration results from a A to T substitution at nucleotide position 452, causing the histidine (H) at amino acid position 151 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
