Variant summary

Our verdict is Likely benign. Variant got -5 ACMG points: 1P and 6B. PP2BP4_ModerateBS2

The NM_005070.4(SLC4A3):c.74C>G(p.Pro25Arg) variant causes a missense change. The variant allele was found at a frequency of 0.00014 in 1,612,746 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/21 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. P25T) has been classified as Uncertain significance.

Ambry Genetics

May 26, 2022

The c.74C>G (p.P25R) alteration is located in exon 3 (coding exon 2) of the SLC4A3 gene. This alteration results from a C to G substitution at nucleotide position 74, causing the proline (P) at amino acid position 25 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
