Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM4 PP3 PP5

The NM_002474.3(MYH11):​c.3722_3793delGGGTCCTGGGCCAGGCCAAGCAGGAGGTGGAACATAAGAAGAAGAAGCTGGAGGCGCAGGTGCAGGAGCTGC​(p.Arg1241_Leu1264del) variant causes a disruptive inframe deletion change involving the alteration of a conserved nucleotide. 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 (no stars).

Genes affected

MYH11 (HGNC:7569): (myosin heavy chain 11) The protein encoded by this gene is a smooth muscle myosin belonging to the myosin heavy chain family. The gene product is a subunit of a hexameric protein that consists of two heavy chain subunits and two pairs of non-identical light chain subunits. It functions as a major contractile protein, converting chemical energy into mechanical energy through the hydrolysis of ATP. A chromosomal rearrangement involving this gene is associated with acute myeloid leukemia of the M4Eo subtype. Mutations in this gene are associated with visceral myopathy, megacystis-microcolon-intestinal hypoperistalsis syndrome 2, and familial thoracic aortic aneurysm 4. [provided by RefSeq, May 2022]

ENSG00000263335 (HGNC:):

NDE1 (HGNC:17619): (nudE neurodevelopment protein 1) This gene encodes a member of the nuclear distribution E (NudE) family of proteins. The encoded protein is localized at the centrosome and interacts with other centrosome components as part of a multiprotein complex that regulates dynein function. This protein plays an essential role in microtubule organization, mitosis and neuronal migration. Mutations in this gene cause lissencephaly 4, a disorder characterized by lissencephaly, severe brain atrophy, microcephaly, and severe cognitive disability. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2012]

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM4: Nonframeshift variant in NON repetitive region in NM_002474.3.
• PP3: No computational evidence supports a deleterious effect, but strongly conserved according to phyloP
• PP5: Variant 16-15726912-TGCAGCTCCTGCACCTGCGCCTCCAGCTTCTTCTTCTTATGTTCCACCTCCTGCTTGGCCTGGCCCAGGACCC-T is Pathogenic according to our data. Variant chr16-15726912-TGCAGCTCCTGCACCTGCGCCTCCAGCTTCTTCTTCTTATGTTCCACCTCCTGCTTGGCCTGGCCCAGGACCC-T is described in ClinVar as Pathogenic. ClinVar VariationId is 14132.Status of the report is no_assertion_criteria_provided, 0 stars.
