Genes affected

SLC37A4 (HGNC:4061): (solute carrier family 37 member 4) This gene regulates glucose-6-phosphate transport from the cytoplasm to the lumen of the endoplasmic reticulum, in order to maintain glucose homeostasis. It also plays a role in ATP-mediated calcium sequestration in the lumen of the endoplasmic reticulum. Mutations in this gene have been associated with various forms of glycogen storage disease. Alternative splicing in this gene results in multiple transcript variants.[provided by RefSeq, Aug 2009]

TRAPPC4 (HGNC:19943): (trafficking protein particle complex subunit 4) Involved in autophagy and endoplasmic reticulum to Golgi vesicle-mediated transport. Part of TRAPP complex. [provided by Alliance of Genome Resources, Apr 2022]

TRAPPC4 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with epilepsy, spasticity, and brain atrophy

  Inheritance: AR Classification: DEFINITIVE, STRONG, LIMITED Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae), ClinGen
• syndromic intellectual disability

  Inheritance: AD Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
