Variant summary

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

The NM_007056.3(CLASRP):c.283C>G(p.Pro95Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000435 in 1,609,890 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 11/19 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. P95L) has been classified as Uncertain significance.

Collection Method: clinical testing

The c.283C>G (p.P95A) alteration is located in exon 4 (coding exon 3) of the CLASRP gene. This alteration results from a C to G substitution at nucleotide position 283, causing the proline (P) at amino acid position 95 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
