• chr1-15341792-G-T
• NM_001391957.1:c.2034G>T
• FHAD1 p.Arg678Arg

Variant summary

Our verdict is Likely benign. The variant received -1 ACMG points: 2P and 3B. PM2 BP4_Moderate BP7

The NM_001391957.1(FHAD1):​c.2034G>T​(p.Arg678Arg) 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. R678R) has been classified as Uncertain significance.
