Collection Method: clinical testing

The c.305A>T (p.Y102F) alteration is located in exon 3 (coding exon 3) of the ZNF277 gene. This alteration results from a A to T substitution at nucleotide position 305, causing the tyrosine (Y) at amino acid position 102 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
