Variant summary

Our verdict is Pathogenic. The variant received 10 ACMG points: 10P and 0B. PVS1 PP5_Moderate

The NM_014780.5(CUL7):​c.3750_3762delAGCTGTCCTGATTinsGC​(p.Ala1251LeufsTer11) variant causes a frameshift, missense change. The variant was absent in control chromosomes in GnomAD project. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Pathogenic (★). Variant results in nonsense mediated mRNA decay.

Genes affected

CUL7 (HGNC:21024): (cullin 7) The protein encoded by this gene is a component of an E3 ubiquitin-protein ligase complex. The encoded protein interacts with TP53, CUL9, and FBXW8 proteins. Defects in this gene are a cause of 3M syndrome type 1 (3M1). Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2009]

KLC4 (HGNC:21624): (kinesin light chain 4) Predicted to be located in cytoplasm and microtubule. Predicted to be part of kinesin complex. [provided by Alliance of Genome Resources, Apr 2022]

LOC124901318 (HGNC:):

ACMG classification

Our verdict: Pathogenic. The variant received 10 ACMG points.

• PVS1: Loss of function variant, product undergoes nonsense mediated mRNA decay. LoF is a known mechanism of disease.
• PP5: Variant 6-43040959-AATCAGGACAGCT-GC is Pathogenic according to our data. Variant chr6-43040959-AATCAGGACAGCT-GC is described in ClinVar as [Pathogenic]. Clinvar id is 1224473.Status of the report is criteria_provided_single_submitter, 1 stars.
