Variant summary

Our verdict is Uncertain significance. The variant received 2 ACMG points: 2P and 0B. PM2

The NM_178499.5(CCDC60):​c.451G>C​(p.Glu151Gln) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.000000684 in 1,461,460 control chromosomes in the GnomAD database, with no homozygous occurrence. 2/3 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E151K) has been classified as Uncertain significance.
