Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 0P and 10B. BP4_Moderate BA1

The NM_020762.4(SRGAP1):c.68-15008C>T variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0797 in 152,186 control chromosomes in the GnomAD database, including 636 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.080 (636 hom., cov: 32)
• Consequence: SRGAP1 NM_020762.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.422

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]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.26).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.122 is higher than 0.05.
