Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 02, 2024The c.736C>T (p.P246S) alteration is located in exon 4 (coding exon 4) of the CHRNA10 gene. This alteration results from a C to T substitution at nucleotide position 736, causing the proline (P) at amino acid position 246 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
