Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_001010985.3(MYBPHL):​c.702T>A​(p.Thr234Thr) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. T234T) has been classified as Benign.

• Frequency: Genomes: not found (cov: 31)
• Consequence: MYBPHL NM_001010985.3 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.813

Genes affected

MYBPHL (HGNC:30434): (myosin binding protein H like) This gene encodes a protein with two immunoglobulin superfamily domains and a fibronectin 3 domain. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2012]

ACMG classification

Verdict is Likely_benign. Variant got -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.83).
• BP7: Synonymous conserved (PhyloP=-0.813 with no splicing effect.
