Genes affected
EMILIN2 (HGNC:19881): (elastin microfibril interfacer 2) Predicted to enable extracellular matrix constituent conferring elasticity. Predicted to be involved in cell adhesion. Located in extracellular region. [provided by Alliance of Genome Resources, Apr 2022]
LPIN2 (HGNC:14450): (lipin 2) Mouse studies suggest that this gene functions during normal adipose tissue development and may play a role in human triglyceride metabolism. This gene represents a candidate gene for human lipodystrophy, characterized by loss of body fat, fatty liver, hypertriglyceridemia, and insulin resistance. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 28, 2022The c.871G>A (p.E291K) alteration is located in exon 4 (coding exon 4) of the EMILIN2 gene. This alteration results from a G to A substitution at nucleotide position 871, causing the glutamic acid (E) at amino acid position 291 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
