FPLD2 (Kobberling-Dunnigan type 2 syndrome) was indicated by the patient's observed clinical characteristics and familial inheritance pattern. A heterozygous mutation within exon 8 of the LMNA gene, as determined by WES, was attributed to a change from cytosine (C) at position 1444 to thymine (T) during the transcription phase. The encoded protein's amino acid at position 482 underwent a mutation, altering it from Arginine to Tryptophan. The LMNA gene mutation serves as a crucial diagnostic marker for Type 2 KobberlingDunnigan syndrome. From the patient's clinical examination, the prescription of hypoglycemic and lipid-lowering medications is considered appropriate.
WES supports the simultaneous clinical evaluation or verification of FPLD2 and can contribute to identifying diseases that demonstrate similar clinical traits. This case study illustrates that familial partial lipodystrophy is associated with an alteration in the LMNA gene, found on chromosome 1q21-22. This case represents one of the few confirmed diagnoses of familial partial lipodystrophy, using the method of whole-exome sequencing.
WES is valuable in the concurrent clinical research into and validation of FPLD2, and it can support the identification of diseases with similar clinical portrayals.

In a limited number of cases of familial partial lipodystrophy, whole-exome sequencing (WES) has yielded a diagnosis; this one is among them.
Coronavirus disease 2019 (COVID-19) is a viral respiratory illness linked to severe damage to other human organs. A novel coronavirus is the culprit behind its global propagation. Currently, several approved vaccine or therapeutic agents are believed to be efficacious in addressing this disease.
