The c.164A>T (p.K55I) alteration is located in exon 2 (coding exon 2) of the ANKRD33 gene. This alteration results from a A to T substitution at nucleotide position 164, causing the lysine (K) at amino acid position 55 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
