Genes affected

PAPSS2 (HGNC:8604): (3'-phosphoadenosine 5'-phosphosulfate synthase 2) Sulfation is a common modification of endogenous (lipids, proteins, and carbohydrates) and exogenous (xenobiotics and drugs) compounds. In mammals, the sulfate source is 3'-phosphoadenosine 5'-phosphosulfate (PAPS), created from ATP and inorganic sulfate. Two different tissue isoforms encoded by different genes synthesize PAPS. This gene encodes one of the two PAPS synthetases. Defects in this gene cause the Pakistani type of spondyloepimetaphyseal dysplasia. Two alternatively spliced transcript variants that encode different isoforms have been described for this gene. [provided by RefSeq, Jul 2008]

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Arg41*) in the PAPSS2 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PAPSS2 are known to be pathogenic (PMID: 22791835, 23633440). This variant is present in population databases (rs201203612, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with brachyolmia (PMID: 31313512). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 932064). For these reasons, this variant has been classified as Pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The PAPSS2 c.121C>T variant is predicted to result in premature protein termination (p.Arg41*). This variant was reported in the homozygous state in two members of a family affected with brachyolmia (Bownass et al 2019. PubMed ID: 31313512). This variant is reported in 0.0054% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/10-89469046-C-T). Nonsense variants in PAPSS2 are expected to be pathogenic. This variant is interpreted as pathogenic. -
