Variant summary

Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM2BP4

The NM_001257359.2(SAMD14):​c.1190A>T​(p.Gln397Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000137 in 1,458,768 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 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. Q397R) has been classified as Uncertain significance.

The c.1274A>T (p.Q425L) alteration is located in exon 11 (coding exon 10) of the SAMD14 gene. This alteration results from a A to T substitution at nucleotide position 1274, causing the glutamine (Q) at amino acid position 425 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
