The c.370G>T (p.D124Y) alteration is located in exon 4 (coding exon 4) of the ANKFN1 gene. This alteration results from a G to T substitution at nucleotide position 370, causing the aspartic acid (D) at amino acid position 124 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
