Genes affected
HECTD1 (HGNC:20157): (HECT domain E3 ubiquitin protein ligase 1) Predicted to enable ubiquitin protein ligase activity. Predicted to be involved in anatomical structure development; positive regulation of proteasomal ubiquitin-dependent protein catabolic process; and protein K63-linked ubiquitination. Predicted to act upstream of or within several processes, including animal organ development; negative regulation of protein localization to plasma membrane; and protein autoubiquitination. [provided by Alliance of Genome Resources, Apr 2022]
AP4S1 (HGNC:575): (adaptor related protein complex 4 subunit sigma 1) This gene encodes a member of the adaptor complexes small subunit protein family. These proteins are components of the heterotetrameric adaptor protein complexes, which play important roles in the secretory and endocytic pathways by mediating vesicle formation and sorting of integral membrane proteins. The encoded protein is the small subunit of adaptor protein complex-4, which is associated with both clathrin- and nonclathrin-coated vesicles. Mutations in this gene are associated with spastic quadriplegic cerebral palsy-6. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 6.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2022The c.6676C>G (p.L2226V) alteration is located in exon 38 (coding exon 37) of the HECTD1 gene. This alteration results from a C to G substitution at nucleotide position 6676, causing the leucine (L) at amino acid position 2226 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
