RCV001193347 | SCV001362104 | pathogenic | Autosomal recessive primary microcephaly | 2019-08-07 | criteria provided, single submitter | clinical testing | Variant summary: ASPM c.9178C>T (p.Gln3060X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. 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. |

RCV000214564 | SCV002230153 | pathogenic | not provided | 2025-01-17 | 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. |

Ambry Genetics | RCV004955250 | SCV005495836 | pathogenic | Inborn genetic diseases | 2024-11-20 | criteria provided, single submitter | clinical testing | The c.9178C>T (p.Q3060*) alteration, located in exon 21 (coding exon 21) of the ASPM gene, consists of a C to T substitution at nucleotide position 9178. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Based on data from gnomAD, the T allele has an overall frequency of 0.002% (5/281152) total alleles studied. The highest observed frequency was 0.014% (5/35320) of Latino alleles. This variant has been identified in the homozygous state in individuals with features consistent with ASPM-related microcephaly (Tan, 2014; Kumar, 2004). Based on the available evidence, this alteration is classified as pathogenic. |
