The variant allele was found at a frequency of 1.6e-05 in 249856 control chromosomes (gnomAD). c.9178C>T has been reported in the literature in individuals affected with Primary autosomal recessive microcephaly (e.g. Kumar_2004). These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two ClinVar submitters (evaluation after 2014) cite the variant as pathogenic. Based on the evidence outlined above, the variant was classified as pathogenic.

Invitae RCV000214564 SCV002230153 pathogenic not provided 2023-12-17 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Gln3060*) in the ASPM gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in ASPM are known to be pathogenic (PMID: 19028728, 23611254). This variant is present in population databases (rs137852994, gnomAD 0.01%). This premature translational stop signal has been observed in individuals with primary microcephaly (PMID: 15355437, 19028728, 23611254). ClinVar contains an entry for this variant (Variation ID: 4960). For these reasons, this variant has been classified as Pathogenic.
