Collection Method: clinical testing

The c.830C>T (p.A277V) alteration is located in exon 8 (coding exon 6) of the KIAA1841 gene. This alteration results from a C to T substitution at nucleotide position 830, causing the alanine (A) at amino acid position 277 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
