Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2024The c.842T>C (p.M281T) alteration is located in exon 8 (coding exon 8) of the NCBP3 gene. This alteration results from a T to C substitution at nucleotide position 842, causing the methionine (M) at amino acid position 281 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
