Description

The AP4M1 c.952C>T variant is predicted to result in premature protein termination (p.Arg318*). This variant was reported in individuals with autosomal recessive spastic tetraplegia (Tüysüz et al. 2014. PubMed ID: 24700674; Table S1, Monies et al. 2019. PubMed ID: 31130284; Table S2, Dong et al. 2020. PubMed ID: 32005694). This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/7-99703604-C-T). Nonsense variants in AP4M1 are expected to be pathogenic. This variant is interpreted as pathogenic.
