Genes affected
MBOAT4 (HGNC:32311): (membrane bound O-acyltransferase domain containing 4) Enables serine O-acyltransferase activity. Involved in peptidyl-serine octanoylation. Predicted to be located in endoplasmic reticulum. Predicted to be active in membrane. Predicted to be integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.287G>A (p.R96H) alteration is located in exon 4 (coding exon 4) of the LEPROTL1 gene. This alteration results from a G to A substitution at nucleotide position 287, causing the arginine (R) at amino acid position 96 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
