Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_019065.3(NECAB2):c.211C>A(p.Arg71Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000372 in 1,613,492 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic 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. R71C) has been classified as Uncertain significance.

Ambry Genetics

Jan 04, 2024

The c.211C>A (p.R71S) alteration is located in exon 2 (coding exon 2) of the NECAB2 gene. This alteration results from a C to A substitution at nucleotide position 211, causing the arginine (R) at amino acid position 71 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
