Genes affected

STBD1 (HGNC:24854): (starch binding domain 1) Enables enzyme binding activity and glycogen binding activity. Involved in glycophagy and intracellular transport. Located in T-tubule; endoplasmic reticulum; and perinuclear region of cytoplasm. Is integral component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

STBD1 links:

FAM47E-STBD1 (HGNC:44667): (FAM47E-STBD1 readthrough) This locus represents naturally occurring read-through transcription between the neighboring FAM47E (family with sequence similarity 47, member E) and STBD1 (starch binding domain 1) genes on chromosome 4. The read-through transcript encodes a protein that shares sequence identity with the upstream gene product but its C-terminal region is distinct due to frameshifts relative to the downstream gene.
