Variant summary
Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PVS1PP5_Moderate
The NM_007347.5(AP4E1):c.2743_2744insTATGT(p.His915LeufsTer29) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000547 in 1,461,652 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★). Synonymous variant affecting the same amino acid position (i.e. H915H) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Spastic paraplegia Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Aug 10, 2023 | For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 569155). This variant has not been reported in the literature in individuals affected with AP4E1-related conditions. This variant is present in population databases (rs754944429, gnomAD 0.02%). This sequence change creates a premature translational stop signal (p.His915Leufs*29) in the AP4E1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in AP4E1 are known to be pathogenic (PMID: 21620353, 21937992, 23472171). - |
