Comment on list classification: Gene identified in literature PMID:30914295 as missing in PanelApp compared to other curated gene list for ID genes.

SRP54 is not associated with a disease phenotype in OMIM, however is probable in Gene2Phenotype identified as SRP54 Disease: Syndromic neutropenia with Shwachman-Diamond-like features, ID is not listed as a phenotype.

The gene has been identified in the following paper - Mutations in signal recognition particle SRP54 cause syndromic neutropenia with Shwachman-Diamond-like features (PMID:28972538).

3 non related families presented with neutropenia associated with a host of various other symptoms, including exocrine pancreatic deficiency (2 of 3 patients) and/or autistic behavior (documented in 2 of 3 patients; not accessible in the third, patient, due to early death).
It should be noted that several potentially pathogenic CNVs encompassing SRP54 have been reported in studies referring to unrelated phenotypes (Supplemental Table 3), and ID/DD phenotype is reported amongst a majority of these individuals.

SRP54 will be classified as Amber and will be added to the watchlist as this is the first time a pathogenic single nucleotide variant or indel has been reported and ID is not the predominant phenotype for the disease presentation.
