Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate

The NM_003943.5(STBD1):​c.70C>T​(p.Arg24Trp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000205 in 1,611,486 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R24P) has been classified as Uncertain significance.

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]
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.
