Variant chr8-2942574-C-G details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The NM_033225.6(CSMD1):c.10433G>C(p.Ser3478Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000759 in 1,448,838 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/19 in silico tools predict a benign outcome for this variant. 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. S3478N) has been classified as Likely benign.

The c.10433G>C (p.S3478T) alteration is located in exon 69 (coding exon 69) of the CSMD1 gene. This alteration results from a G to C substitution at nucleotide position 10433, causing the serine (S) at amino acid position 3478 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
