Dec 06, 2022

The c.335C>T (p.A112V) alteration is located in exon 4 (coding exon 3) of the HDHD2 gene. This alteration results from a C to T substitution at nucleotide position 335, causing the alanine (A) at amino acid position 112 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
