Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 22, 2022The c.776G>C (p.C259S) alteration is located in exon 7 (coding exon 6) of the SAMD14 gene. This alteration results from a G to C substitution at nucleotide position 776, causing the cysteine (C) at amino acid position 259 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
