Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1309C>T (p.R437C) alteration is located in exon 11 (coding exon 10) of the SAMD14 gene. This alteration results from a C to T substitution at nucleotide position 1309, causing the arginine (R) at amino acid position 437 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

PreventionGenetics, part of Exact Sciences

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The SAMD14 c.1309C>T variant is predicted to result in the amino acid substitution p.Arg437Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.025% of alleles in individuals of East Asian descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
