Variant 1-16400797-G-T 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_198546.1(SPATA21):c.1097C>A(p.Pro366His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000062 in 1,611,956 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 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. P366S) has been classified as Uncertain significance.

The c.1097C>A (p.P366H) alteration is located in exon 11 (coding exon 9) of the SPATA21 gene. This alteration results from a C to A substitution at nucleotide position 1097, causing the proline (P) at amino acid position 366 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
