The c.1742A>T (p.H581L) alteration is located in exon 14 (coding exon 13) of the PHF20L1 gene. This alteration results from a A to T substitution at nucleotide position 1742, causing the histidine (H) at amino acid position 581 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
