GeneDx	RCV000767190	SCV000621999	uncertain significance	not provided	2017-11-03	criteria provided, single submitter	clinical testing	A variant of uncertain significance has been identified in the CENPJ gene. The P411S variant has notbeen published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. This variant is observed in 30/126618 (0.02%) alleles from individuals of European background, in large population cohorts (Lek et al., 2016). The P411S variant is a non-conservative amino acidsubstitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, this substitution occurs at a position that is not conserved, and in silico analysis predicts this variant likely does not alter the proteinstructure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
Illumina Laboratory Services, Illumina	RCV001112981	SCV001270701	uncertain significance	Seckel syndrome 4	2018-01-12	criteria provided, single submitter	clinical testing	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score, this variant could not be ruled out of causing disease and therefore its association with disease required further investigation. A literature search was performed for the gene, cDNA change, and amino acid change (if applicable). No publications were found based on this search. This variant was therefore classified as a variant of unknown significance for this disease.

Labcorp Genetics (formerly Invitae), Labcorp	RCV000767190	SCV002201799	uncertain significance	not provided	2022-06-14	criteria provided, single submitter	clinical testing	This sequence change replaces proline, which is neutral and non-polar, with serine, which is neutral and polar, at codon 411 of the CENPJ protein (p.Pro411Ser). This variant is present in population databases (rs145433187, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with CENPJ-related conditions. ClinVar contains an entry for this variant (Variation ID: 434714). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The serine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
Ambry Genetics	RCV004609409	SCV005102998	uncertain significance	Inborn genetic diseases	2024-05-06	criteria provided, single submitter	clinical testing	The c.1231C>T (p.P411S) alteration is located in exon 7 (coding exon 6) of the CENPJ gene. This alteration results from a C to T substitution at nucleotide position 1231, causing the proline (P) at amino acid position 411 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
