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]

EMILIN2 links:

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]

Collection Method: clinical testing

The c.608C>T (p.S203F) alteration is located in exon 4 (coding exon 4) of the EMILIN2 gene. This alteration results from a C to T substitution at nucleotide position 608, causing the serine (S) at amino acid position 203 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
