The variant allele was found at a frequency of 0.475 in 152,038 control chromosomes in the GnomAD database, including 18,129 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 0.48 (18129 hom., cov: 32)
• Consequence: GAS7 NM_201433.2 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.529

Genes affected

GAS7 (HGNC:4169): (growth arrest specific 7) Growth arrest-specific 7 is expressed primarily in terminally differentiated brain cells and predominantly in mature cerebellar Purkinje neurons. GAS7 plays a putative role in neuronal development. Several transcript variants encoding proteins which vary in the N-terminus have been described. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.562 is higher than 0.05.
