Variant summary
Our verdict is Pathogenic. The variant received 16 ACMG points: 16P and 0B. PVS1PP5_Very_Strong
The ENST00000330775.9(SLC37A4):c.345dupG(p.Leu116AlafsTer15) variant causes a frameshift change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000361 in 1,605,154 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Pathogenic (★★). Synonymous variant affecting the same amino acid position (i.e. G115G) has been classified as Likely benign. Variant results in nonsense mediated mRNA decay.

Glucose-6-phosphate transport defect Pathogenic:2
This sequence change creates a premature translational stop signal (p.Leu116Alafs*15) in the SLC37A4 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SLC37A4 are known to be pathogenic (PMID: 9758626, 10940311). This variant is present in population databases (rs782604758, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with SLC37A4-related conditions. ClinVar contains an entry for this variant (Variation ID: 529223). For these reasons, this variant has been classified as Pathogenic. -
