Genes affected

AP4M1 (HGNC:574): (adaptor related protein complex 4 subunit mu 1) This gene encodes a subunit of the heterotetrameric AP-4 complex. The encoded protein belongs to the adaptor complexes medium subunits family. This AP-4 complex is involved in the recognition and sorting of cargo proteins with tyrosine-based motifs from the trans-golgi network to the endosomal-lysosomal system.

Hereditary spastic paraplegia 50

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	3billion	May 22, 2022	Stop-gained (nonsense): predicted to result in a loss or disruption of normal protein function through nonsense-mediated decay (NMD) or protein truncation. Multiple pathogenic variants are reported downstream of the variant. The variant is observed at an extremely low frequency in the gnomAD v2.1.1 dataset (total allele frequency: <0.001%). The variant has been reported to be associated with AP4M1 related disorder (ClinVar ID: VCV000522944). Therefore, this variant is classified as pathogenic according to the recommendation of ACMG/AMP guideline. -
