Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 11, 2023The c.892A>T (p.T298S) alteration is located in exon 8 (coding exon 7) of the SAMD14 gene. This alteration results from a A to T substitution at nucleotide position 892, causing the threonine (T) at amino acid position 298 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
