Genetic Variant NM_178499.5:c.357G>C (chr12-119479109-G-C) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_178499.5(CCDC60):c.357G>C(p.Glu119Asp) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000026 in 1,612,776 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. E119K) has been classified as Uncertain significance.

The c.357G>C (p.E119D) alteration is located in exon 4 (coding exon 4) of the CCDC60 gene. This alteration results from a G to C substitution at nucleotide position 357, causing the glutamic acid (E) at amino acid position 119 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
