Genes affected
MYOT (HGNC:12399): (myotilin) This gene encodes a cystoskeletal protein which plays a significant role in the stability of thin filaments during muscle contraction. This protein binds F-actin, crosslinks actin filaments, and prevents latrunculin A-induced filament disassembly. Mutations in this gene have been associated with limb-girdle muscular dystrophy and myofibrillar myopathies. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.[provided by RefSeq, Oct 2008]
PKD2L2-DT (HGNC:55557): (PKD2L2 divergent transcript)

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -19 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_noAF, Cadd, Dann, Eigen, phyloP100way_vertebrate, PrimateAI, PROVEAN [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
BP4
Computational evidence support a benign effect (MetaRNN=0.034995645).
BP6
Variant 5-137877559-G-C is Benign according to our data. Variant chr5-137877559-G-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 260036.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000171 (26/152202) while in subpopulation EAS AF = 0.00482 (25/5186). AF 95% confidence interval is 0.00335. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 26 AD gene.
