Genetic Variant CD101:p.Ser887Pro (chr1-117025739-T-C) – ACMG Classification: Likely_benign (-2 pts)

Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2BP4_Strong

The NM_001256106.3(CD101):c.2659T>C(p.Ser887Pro) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000161 in 1,614,174 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/21 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. S887L) has been classified as Uncertain significance.

The c.2659T>C (p.S887P) alteration is located in exon 8 (coding exon 8) of the CD101 gene. This alteration results from a T to C substitution at nucleotide position 2659, causing the serine (S) at amino acid position 887 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
