With great interest, we read Zrhidri et al.’s paper  which reports compound heterozygous mutations in exon 4 and 9 of the GNPTG gene, in a familial scleroderma-like disease. This novel finding represents an important addition to the family of genetic mutations previously associated with multisystemic fibrosis and scleroderma-like diseases in literature. Further, elucidating pathogenetic mechanisms of genetic systemic fibrosis could potentially lead to discovery of effective treatment of auto-immune systemic sclerosis and related diseases, and alleviate severe morbidity and mortality.
FAM 111B gene for scleroderma and multisystemic fibrosis-like hereditary fibrosing poikiloderma with tendon contractures, myopathy, and pulmonary fibrosis (POIKTMP) 
RECQL4 gene for Rothmund Thomson Syndrome (RTS) ,
WRN gene for Werner syndrome (WS) 
LMNA gene in Hutchinson-Gilford progeria syndrome (HGPS) 
Finally, considering the multifactorial etiology of fibrosis, it would be interesting to see how the new gene (GNPTG) compares to other genes involved in scleroderma-like diseases such as FAM 111B (POIKTMP), RECLQL4 (RTS), WRN (WS) and LMNA (HGPS); and if there are possible gene interactions, considering the similarities in the phenotype produced.
