Collection Method: clinical testing

The c.298C>T (p.P100S) alteration is located in exon 2 (coding exon 1) of the BAHD1 gene. This alteration results from a C to T substitution at nucleotide position 298, causing the proline (P) at amino acid position 100 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
