Variant summary

Our verdict is Pathogenic. The variant received 14 ACMG points: 14P and 0B. PVS1_ModeratePS3PP5_Very_Strong

The NM_000281.4(PCBD1):​c.292C>T​(p.Gln98*) variant causes a stop gained change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000197 in 1,614,068 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). ClinVar reports functional evidence for this variant: "SCV002252383: Experimental studies have shown that this premature translational stop signal affects PCBD1 function (PMID:24204001)." and additional evidence is available in ClinVar. Synonymous variant affecting the same amino acid position (i.e. Q98Q) has been classified as Likely benign.

Genes affected
PCBD1 (HGNC:8646): (pterin-4 alpha-carbinolamine dehydratase 1) This gene encodes a member of the pterin-4-alpha-carbinolamine dehydratase family. The encoded protein has been identified as a moonlighting protein based on its ability to perform mechanistically distinct functions. The encoded protein functions as both a dehydratase involved in tetrahydrobiopterin biosynthesis, and as a cofactor for HNF1A-dependent transcription. A deficiency of this enzyme leads to hyperphenylalaninemia. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2014]
SGPL1 (HGNC:10817): (sphingosine-1-phosphate lyase 1) Enables sphinganine-1-phosphate aldolase activity. Involved in apoptotic signaling pathway; fatty acid metabolic process; and sphingolipid metabolic process. Located in endoplasmic reticulum. Implicated in nephrotic syndrome type 14.

ACMG classification

Classification was made for transcript

Our verdict: Pathogenic. The variant received 14 ACMG points.

PVS1
Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.073 CDS is truncated, and there are 2 pathogenic variants in the truncated region.
PS3
PS3 evidence extracted from ClinVar submissions: SCV002252383: Experimental studies have shown that this premature translational stop signal affects PCBD1 function (PMID: 24204001).; SCV004848890: in vitro functional studies suggest that this variant impacts protein expression or function (Thony 1998 PMID: 9585615, Ferré 2014 PMID: 24204001).; SCV005201366: Published functional studies suggest this variant is unable to drive transcriptional co-activation in conjunction with HNF1b (PMID: 24204001)
PP5
Variant 10-70883973-G-A is Pathogenic according to our data. Variant chr10-70883973-G-A is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 16799.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
